    .(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.

    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.

    .Name: CytoKeratin 20 Antibody Clone Ks20.8

    Description and aplications: Keratins (also known as cytokeratins) are intermediate filament/forming proteins that represents the main cytoskeleton of epithelial cells. They classically are classified based on Moll cataloging which grouped the basic-to-neutral type II keratins as K1–K8 and the acidic type I keratins as K9– K19. An updated classification including 24 types of keratins was then proposed in order to enable other mammalian species keratins to be added.  Keratin 20 / cytokeratin20 (CK20) is a Type-I keratin which is primarily expressed in gastric and intestinal epithelium, urothelium, and Merkel-cells. CK20 is expressed in adenocarcinomas of the colon, stomach, pancreas and the bile system. CK20 is also present in mucinous ovarian tumors, transitional-cell and Merkel cell carcinomas. Notably, the squamous cell carcinomas and adenocarcinomas of the breast, lung, and endometrium, nonmucinous tumors of the ovary, and small cell carcinomas lack in CK20.

    Composition: anti human keratin 20 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: BOB-1 (SP92)

    Description and applications: The BOB.1, OBF.1, OCA-B (now called BOB.1 / OBF.1) is a 35 kD protein encoded by a gene located on chromosome 11q23.1. BOB.1 from “B cell binding Octamer protein 1 “is a specific coactivator of transcription factors Oct-1 and Oct-2 of B lymphocytes. BOB.1 mission is to increase transcriptional activity of such proteins. Interaction with transcription factor OCT2 octamer ATGCAAAT nucleotides is critical and decisive for the expression of immunoglobulin genes. It has been recently demonstrated that alteration in immunoglobulin transcription is correlated with the downregulation of the transcription factors Oct-2 and BOB.1 / OBF.1 on B lymphocytes. This antibody recognizes BOB.1 of human, murine and rat origin. In normal lymphoid tissue, BOB.1 is expressed mainly in the nuclei of germinal center B lymphocytes, with lower intensity in the follicular mantle and dispersed form in B lymphocytes localized in the interfolicular areas of the lymphoid tissue; for this reason it is useful in identifying B cell lymphomas. Variable intensity has been demonstrated in Hodgkin disease, classic type without statistical relationship with its different subtypes. The expression of specific activator proteins of B lymphocytes like “octamer-binding transcription factor 2” [Oct-2] and BOB.1 with pan-B lymphocyte markers (CD20 or CD79a ) are useful for the differential diagnosis of diffuse large B-cell lymphoma, nodular lymphocyte-predominant Hodgkin lymphoma (OCT-2 + / BOB.1 + / PAN-B +) with anaplastic lymphoma B (OCT-2 / BOB. 1- / PAN-B +). The antibody shows no cross-react with Oct-1 or Oct-2.

    .(Name: EGFR (Epidermal growth factor receptor) Antibody (Clone EP22

    Description and applications: The epidermal growth factor receptor (EGFR) is a transmembrane glycoprotein of 170 kDa with tyrosine-kinase activity after binding to the epidermal growth factor (EGF) and is involved in cell growth and differentiation. Tyrosine(Tyr) residues Tyr 1068, Tyr 1148 and Tyr 1173 located at the carboxy (C) terminal portion of the EGFR, are the places of autophosphorylation upon binding with the EGF. Determining the level of expression of EGFR is necessary to establish a specific treatment with monoclonal antibodies (cetuximab). The EGFR is overexpressed in some tumors of the colon, esophagus, stomach, breast, CNS, bladder, lung, head and neck, uterine cervix, vulva, ovary and endometrium. EGFR is expressed in a high percentage of metastases of squamous cell carcinomas of different locations and therefore its expression has been considered as an indicator of poor prognosis in these tumors. The antibody detects both EGFR phosphorylated on Tyr1068 of the mature human isoform 1 (corresponding to Y1092 from the precursor form P00533-1/p170), and also unphosphorylated EGFR.

    Composition: anti-human EGFR rabbit monoclonal antibody purified by protein affinity and prepared in 10mM PBS, pH 7.4, with 0.2% BSA and 0.09% sodium azide.
