    Name: CD23 Monoclonal Antibody clone SP23

    Description and applications: The role of IgE immunoglobulins in the initiation and development of acute allergic processes is well known. These processes are generally initiated through its interaction with high affinity receptors for Fc portion (FceRI) located mainly on the surface of mast cells and basophil granulocytes where it regulates exocytosis phenomena and subsequent degranulation of mediators of hypersensitivity reactions type I. Furthermore, the immunoglobulin IgE also binds specifically to an integral membrane glycoprotein of 45- 55 kDa type 2 (321 aa) that does not belong to the immunoglobulin superfamily but to the selectins and are included under the name of low affinity receptor of IgE (FceRIIa+b / CD23). CD23 is expressed in a wide range of cell types, including B lymphocytes, eosinophils, granulocytes,  platelets, T and NK cells, dendritic reticulum cells and Langerhans cells. CD23 expression has been detected in neoplastic lymphoid cells of chronic lymphocytic leukemia, in a variable percentage of follicular lymphomas and in a small proportion of large B-cell lymphomas. Furthermore and although the CD23 molecule is produced by B cells, is adsorbed in a large amount on follicular dendritic reticulum cells thus is also used for the identification of its neoplasms (dendritic reticulum cell sarcoma).

    Composition: anti-CD23 mouse monoclonal antibody obtained from supernatant culture and prediluted in a tris buffered solution pH 7.4 containing 0.375mM sodium azide solution as bacteriostatic and bactericidal.

    Name:Mouse anti-human anti-CD44 Std./HCAM Monoclonal Antibody Clone SP37.

    Description and aopplications: CD44 is a transmembrane type I glycoprotein involved in adhesion between cells and different  components of the extracellular matrix, expr many human tissues.  CD44 is also known as homing cell adhesion molecule (H-CAM), Phagocytic glycoprotein-1 (PgP-1), ECM-III, HUTCH-1, or Hermes-1. This antibody recognize CD44 standard isoform (CD44std), which comprises exons 1-5 and 16-20, present in most cells as a glycoprotein of approximately 90 kDa that acts as the main ligand for hyaluronic acid. For its behavior as a receptor for hyaluronic acid, CD44s molecule which is expressed on leukocytes including many T and B lymphocytes, medullary thymocytes, monocytes and granulocytes, plays an important role in intercellular adhesion of cells to the basement membrane and in maintaining its polarity. In tumors, the loss of CD44s expression is generally considered a factor of poor prognostic and in most cases is associated with the presence of distant metastases. Besides determining CD44s may be useful in the diagnosis of malignant urothelial lesions in their early stages, which would be characterized by a membrane staining restricted to the basal layers of the transformed epithelium compared with diffuse staining normally present in the normal urothelium.

    Composition: anti-human CD44std mouse monoclonal antibody purified from ascites fluid by Protein A chromatography. Prepared in 10mM PBS, pH 7.4, with 0.2% BSA and 0.09% sodium azide.

    (Name:Mouse Anti-p27 Monoclonal Antibody (Clone EP104

    Description and aplications: This antibody recognizes a protein of 27 kDa identified as p27kip1, a mitotic inhibitor cell cycle regulator. The epitope extends between amino acids 83 to 197 of p27. This antibody is highly specific and does not cross react with other mitotic inhibitors. The p27 functions as a negative regulator of G1 progression and has been proposed as a possible mediator of cell G1 arrest induced by TGF-Beta. Is structurally related with Kip1 Cip1 / WAF1, with a similar sequence of 60 amino acids at the N-terminal region. In vitro, p27Kip1 strongly binds to cyclin D-Cdk4, cyclin E-Cdk2 and cyclin A-Cdk2 and inhibits cdk activity. In normal cells the level of Kip1 activity gradually decreases as the cells reach the stage S. The addition of TGF-b in early G1 prevents this decrease of activity, apparently by preventing Kip1 sequestration that occurs in cells that have not been treated with this factor. The treatment with TGF-b also reduces the levels of Cdk4. Kip1 preferentially binds to cyclin D-Cdk4, but the lower levels of Cdk4 in cells treated by TGF-b, presumably allow for some of the Kip1 to bind to the cyclin E-Cdk2 and cyclin A-Cdk2.

    Composition: anti-p27 mouse monoclonal antibody obtained from supernatant culture and prediluted in atris  buffered solution pH 7.4 containing 0.375mM sodium azide solution as bacteriostatic and bactericidal.

    (Name: Rabbit anti-human Carbonic Anhydrase 9 Monoclonal Antibody (Clone EP161.

    Description and applications: Carbonic anhydrases (CAs) are a large family of zinc metalloenzymes that catalyze the reversible hydration of carbon dioxide. They participate in a variety of biological processes, including respiration, calcification, acid-base balance, bone resorption, and the formation of aqueous humor, cerebrospinal fluid, saliva, and gastric acid. They show extensive diversity in tissue distribution and subcellular localization. Carbonic Anhydrase 9, a member of the carbonic anhydrase family, is thought to play a role in the regulation of cell proliferation in response to hypoxic conditions and may be involved in oncogenesis and tumor progression.Carbonic Anhydrase 9 (CA9) has a distinctive expression pattern in normal and cancer tissues. The most abundant expression of CA9 was found in normal mucosa of the stomach and gallbladder. Other normal tissues have lower or no expression. Relatively high levels of CA9 are expressed in carcinomas of the cervix, kidney, lung, breast and many other tumors. Most studies have shown that decreased CA9 levels are independently associated with poor survival. Low levels of CA9 maybe benefit more from adjuvant treatment than patients with high levels.

    COMPOSITION: Anti-human Carbonic Anhydrase 9 rabbit monoclonal antibody purified from serum and prepared in 10mM PBS, pH 7.4, with 0.2% BSA and 0.09% sodium azide.

    IMMUNOGEN: A synthetic peptide corresponding to residues in the extracellular domain in human Carbonic Anhydrase 9 was used as an immunogen.

    .(Name: Mouse anti-human Cathepsin K Monoclonal Antibody (Clone 3F9

    Description and Applications: Cathepsin K is a lysosomal papain–like cystine proteinase and can be expressed in normal osteoblasts, fibroblasts, and skin. Recently, cathepsin K has been reported as useful in distinguishing translocation renal cell carcinoma (RCC) from other subtypes of RCC. Mortignoni et al. tested 17 cases of translocation RCC and found that cathepsin K stained 6 of 8 cases of translocation RCC with t(X;1), all seven cases of translocation RCC with t(6;11), but was negative for one case with t(X;3) and one with t(X;17).1 Additionally, the study compared IHC detection of TFE3 antibody in the 17 cases and demonstrated that all translocation RCC with t(6;11) were completely negative for TFE3, but positive for cathepsin K; all other translocation RCC with different chromosomal tranlocations other than t(X;1) expressed TFE3. Thus, it is recommended that antibodies against both TFE3 and cathepsin K should be used for evaluating translocation renal cell carcinomas. None of the 305 other renal cell neoplasms representing the most common renal cell neoplasm subtypes were positive for cathepsin K. Zheng et al. reported only 2.7% of 1,140 carcinomas from various organs exhibited cathepsin K labeling, indicating that among carcinomas cathepsin K labeling is highly specific for translocation RCC and can be used to help differentiate translocation RCC from other carcinomas.

    COMPOSITION: Anti-human Cathepsin K mouse monoclonal antibody purified from serum and prepared in 10mM PBS, pH 7.4, with 0.2% BSA and 0.09% sodium azide.

    Rated 0 out of 5

    .(Name: Mouse anti-human Cytokeratin Monoclonal Antibody (Clone AE1

    Description and applications: Due to the high homology among the different molecules, it is common for a monoclonal antibody to react with different types of cytokeratins; for example, anti-cytokeratin AE1 labels medium molecular weight acidic cytokeratins 10, 14, 15, 16, and 19, and low molecular weight acidic cytokeratin 19. Proteins generically called intermediate filaments, because they measure between 7 and 22 nm in diameter (i.e., with a size between actin, 5-7 nm, and tubulin, 22-25 nm), are part, along with actin and tubulin, of the vertebrate cytoskeleton. This superfamily is composed of six subfamilies of molecules with different tissue expression patterns. Cytokeratins constitute homology groups I and II, and in humans they are encoded by more than 49 different genes located in chromosomes 17 (I) and 12 (II). The nomenclature chosen in 1982 by Moll and Franke assigns numbers from 1 to 8 to type II cytokeratins (neutral or basic) and from 9 to 21 to type I cytokeratins (acidic). An analogous nomenclature for hair keratins has now been defined, with the addition of letters Ha and Hb to distinguish type I from type II. Structurally, cytokeratins share with the rest of intermediate filaments a central axisof 310 amino acid residues consisting of four highlypreserved α-helical domains (1A, 1B, 2A, and 2B) that define the type of intermediate filament that will be formed after assembly; these domains are separated by three non-helical linking regions (L1, L12, and L2) and two end domains which are highly different in, size and sequence (head, 1, and tail, 2), each with constant (E1/E2), variable (V1/V2), and homology (H1/H2) regions, the latter characteristic of type II keratins and absent in type I keratins. The major immunogenic properties and the main differences between each keratin class are found in the variable domains. Keratins are usually assembled into I/II heterodimers and are specifically co-expressed in pairs in each tissue. This antibody is widely reactive and labels almost all types of epithelia, thus being one of the best antibodies for the preliminary screening of neoplasms of an epithelial origin, and specially for the identification of malignant metastatic tumours of this origin. It does not react against all hepatocarcinomas, basal cell carcinomas, and adrenocortical carcinomas, and it partially reacts against renal cell carcinomas, small cell lung carcinomas, and large-cell carcinomasof the lung.

    Description and applications: Due to the high homology among the different molecules, it is common for a monoclonal antibody to react with different types of cytokeratins; for example, anti-cytokeratin AE3 labels high molecular weight basic cytokeratins 1, 2, 3, 4, 5, and 6, as well as low molecular weight basic cytokeratins 7 and 8. Proteins generically called intermediate filaments, because they measure between 7 and 22 nm in diameter (i.e., with a size between actin, 5-7 nm, and tubulin, 22-25 nm), are part, along with actin and tubulin, of the vertebrate cytoskeleton.

    Name: Mouse Anti-Human Keratin AE1-AE3 Cocktail Antibody clone AE1-AE3

    Description and applications: The nomenclature coined in 1982 by Moll and Franke assigned ranges from 1 to 8 for keratin type II (neutral or basic) and between 9 and 21 for type I (acidic). However and because of the high homology among the different molecules is common for a single monoclonal antibody to react with different types of keratins. This antibody, comprising a cocktail of AE1 and AE3 monoclonal antibodies, simultaneously recognizes keratins 10, 14, 15, 16 and 19 and 1, 2, 3, 4, 5, 6, 7 and 8, so that it is considered as one of the broadest spectrum reagents for the identification of epithelial origin in a given neoplasm. However, it should be borne in mind that besides hepatocarcinomas other tumors that often can be negative to the antibody AE1-AE3 are kidney, adrenal, prostate and neuroendocrine carcinomas. For these reasons the AE1-AE3 keratin antibody should be used in conjunction with other broad spectrum keratins.

    Composition: anti-Keratin AE1-AE3 mouse antibody obtained obtained from mouse ascites by protein A chromatography in a tris buffered solution pH 7.4 containing 0.375mM sodium azide solution as bacteriostatic and bactericidal. The quantity of the active antibody in the sample is of approximately 4 μ/mL..

    .(Name: Mouse anti-human Cytokeratin5/6 Monoclonal Antibody (Clone EP24/EP67

    Description and applications: Keratins are cytoplasmic intermediate filament proteins expressed by epithelial cells. CK5 is a type II cytokeratin. Loss-of-function mutations in the keratin 5 gene (KRT5) affected family members and in six unrelated patients with Dowling-Degos disease (DDD), an autosomal  dominant genodermatosis. This suggests a crucial role for keratins in the organization of cell adhesion, melanosome uptake, organelle transport, and nuclear anchorage. CK5 labels myoepithelial cells of breast and prostate basal cells. CK5 and calretinin have been useful in different studies as immunohistochemical markers suggestive of mesothelioma, and their expression is analyzed for the histological differentiation with adenocarcinomas, especially when confronting metastatic tumors of unknown origin. The human type II Cytokeratin 6 (CK6; 56 kDa) is well known for its strong induction in stratified epithelia that feature an enhanced cell proliferation rate or abnormal differentiation during wound healing, in several diseases (e.g. psoriasis, actinic keratosis) and cancer. CK6 is expressed on stratified epithelia including oral mucosa, esophagus, basal layer of epidermis, the outer root sheath of hair follicles, and in glandular epithelia. CK6 is a marker of hyperproliferative and activated keratinocytes found in psoriasis.Anti-CK6 paired with the CK5 antibody is useful for differentiating mesothelioma (positive) from lung carcinoma (negative) or metastatic carcinoma (negative) in the pleura. An antibody against CK5/6 has also been used to distinguish usual ductal hyperplasia of the breast (strong staining) from solid papillary DCIS (negative).

    Name: Rabbit anti-human Gross Cystic Disease Fluid Protein-15 (BRST-2/GCDFP-15) Monoclonal Antibody (Clone EP95).

    Description and Applications: Gross cystic disease fluid protein (GCDFP-15), also called prolactininducible protein (PIP), is a single polypeptide chain with a versatile function in human reproductive and immunological systems. GCDFP-15 binds to CD4, exerts a potent inhibition on T lymphocyte apoptosis mediated by CD4/T-cell receptor (TCR) activation, and carries a fibronectinspecific aspartyl protease activity. It is up regulated by prolactin and androgens, while it is down regulated by estrogen. In normal adult tissues, GCDFP-15 expression was found in all apocrine, lacrimal, ceruminous, and Moll’s glands and in numerous serous cells of the submandibular, sublingual, and minor salivary glands. The serous cells of nasal and bronchial glands were also positive. It is used as a marker of apocrine differentiation. GCDFP-15 has been found in the cyst fluid of cystic breast disease and primary and metastatic breast cancer, and considered a highly specific marker for identification of breast cancer. GCDFP-15 expression has also been found in other cancer types including salivary glands, sweat glands, prostate, and lung.

    COMPOSITION: Anti-human BRST-2/GCDFP-15 rabbit monoclonal antibody purified from serum and prepared in 10mM PBS, pH 7.4, with 0.2% BSA and 0.09% sodium azide.

    Name: Cytokeratin HMW Antibody clone 34BE12

    Description and applications: The proteins generically known intermediate filaments measuring between 7 and 22 nm diameter (ie with a size between -5 to 7 nm like actin and 22 to 25 nm like tubulin), are part, together with the above mentioned, of the vertebrates cytoskeleton. This superfamily comprises six subfamilies of molecules with different tissue expression. Cytokeratins constitute two homology groups (I and II) and in humans are encoded by more than 49 different genes on chromosomes 17 (I) and 12 (II). The nomenclature coined in 1982 by Moll and Franke assigns ranges of 1 to 8 for type II cytokeratins (neutralor basic) and between 9 and 21 for type I (acidic). Normally, keratins are assembled in heterodimers I / II and are co-expressed in pairs specific to each tissue. This antibody recognizes keratins of 68, 58, 56.5 and 50 kD obtained from the skin stratum corneum. By immunohistochemistry, the antibody reacts with squamous epithelium, ductal epithelia and other similar structure. This antibody is used confirm carius types of tumors like breast, pancreatic, bile duct, salivary gland, prostate and transitional cell carcinoma.

    Composition: anti-HMW-CK mouse monoclonal antibody obtained from supernatant culture and prediluted in a tris buffered solution pH 7.4 containing 0.375mM sodium azide solution as bacteriostatic and bactericidal.

    Immunogen: Solubilized keratin extracted from human stratum corneum.
