Name: INI-1 (BAF47/SNF5) Antibody (Clone 25/BAF47)

Description and applications: SWI/SNF complexes facilitate gene activation and transcription factor binding by altering repressive chromatin structures in an ATP-dependent manner. In mammals, SWI/SNF complexes are present in mutliple forms that include 9-12 BRG1-associated factors (BAFs) per complex. These BAF proteins range in molecular weight from 47 to 250 kDa. BAF47/SNF5 (SMARCB1/Ini1) complexes with BRG1- and BRM-containing SWI/SNF complexes. BAF47/SNF5 mRNA is widely expressed in cell lines and tissues, and BAF47/SNF5 gene is mutated in many human tumors. The latter is indicative of a tumor suppressor role for BAF47/SNF5. In addition, mice deficient for BAF47 die early in embryogenesis, while BAF47/SNF5 heterozygous mice display a variety of tumors in the soft tissues of the head and neck. BAF47/SNF5 also binds the HIV-1 integrase and stimulates integrase-mediated DNA joining activity. Thus, BAF47/SNF5 is a component of SWI/SNF complexes that may be critical for normal development and tumor suppression, but may also be a protein utilized for viral DNA integration into host DNA. Expression in normal tissues is ubiquitous. In tumor tissue loss of protein expression SMARCB1 / INI1 gene was first observed in all malignant rhabdoid tumors of childhood of different location (soft tissue, kidney and CNS) and in medullary carcinomas of the kidney. Also loss of expression is observed in 50% of synovial sarcomas, some myxoid chondrosarcoma and myoepithelial carcinomas, almost all epithelioid sarcoma (proximal and conventional variants) and 50% of malignant tumors of peripheral nerves sheat, all presenting rhabdoid morphology. Loss of immunohistochemistry expression is also observed in cases of poorly differentiated chordoma. The antibody is useful in differentiating rhabdoid tumors of other tumors with similar morphology as desmoplastic round cell tumor, rhabdomyosarcoma and Wilms tumor do not show loss of expression of INI1. The antibody also is useful in confirming the diagnosis of medullary carcinoma and discard possible renal pelvis urothelial carcinoma or other carcinomas of the kidney showing expression for INI1. Maintained staining in most carcinomas, epithelioid angiosarcoma, mesotheliomas, melanomas and other tumors or lesions reagents (granulomas) of epithelioid morphology make this useful antibody in the diagnosis of epithelioid sarcoma.

Composition: anti-human INI-1 mouse monoclonal antibody purified from serum and prepared in 10mM PBS, pH 7.4, with 0.2% BSA and 0.09% sodium azide.

Immunogen: mouse BAF47 aminoacids 257-359.

Name: Muscle Specific Actin,Antibody (Clone HHF35)

Description and applications: Actin is a major component of the cytoskeleton. This antibody recognizes actin of skeletal, cardiac, and smooth muscle cells. It is not reactive with other mesenchymal cells except for myoepithelium. Actin can be resolved on the basis of its isoelectric points into three distinctive components: alpha, beta and gamma in order of increasing isoelectric point. Anti- Muscle-Specific Actin recognizes alpha and gamma isotypes of all muscle groups. Non-muscle cells such as vascular endothelial cells and connective tissues are non-reactive. Also, neoplastic cells of non-musclederived tissue such as carcinomas, melanomas, and lymphomas are negative. This antibody is useful in the identification of rhabdoid cellular elements.

This antigen is expressed in the normal breast epithelium, melanocytes, mast cells and glia. This antibody is recommended to identify oncoprotein expression c-kit in a variety of normal and neoplastic tissues, including gastrointestinal stromal tumors (GIST). It is also expressed in testicular seminoma, small cell carcinomas of the lung, breast carcinomas, glioblastomas, melanomas, and chronicmyeloid leukemias or acute myeloid leukemias in myeloid blast crisis.

Name:CD138 Antibody clone EP201

Description and applications: CD138, also known as Syndecan-1, is a member of the transmembrane heparan sulfate proteoglycan family, acts as an extracellular matrix receptor and is involved in many cellular functions, including cell-cell adhesion and cell-matrix adhesion. CD138 expression is found in both hematopoietic and non-hematopoietic cells. In the hematopoietic system, CD138 labels plasma cells. It is an excellent marker for plasmacytic differentiation within the spectrum of hematologic malignancy. It´s a very usefull tool in the diagnostic of chronic endometritis associated with infertility. Among nonhematolymphoid cells, CD138 reactivity is observed inmany types of epithelial cells and stoma cells in both normal and tumor tissues. These staining should
be remembered and not interpreted as unspecific.

Composition:Anti-human CD138 rabbit monoclonal antibody purified from serum and prepared in 10mM PBS, pH
7.4, with 0.2% BSA and 0.09% sodium azide

Intended use: Immunohistochemistry (IHC) on paraffin embedded tissues. Not tested on frozen tissues or Western-Blotting

Name: CD14 Antibody (Clone EP128)

Description and applications:CD14 is a 55-kDa protein found as a glycosylphosphatidylinositol (GPI)- anchored protein on the surface of monocytes, macrophages, and polymorphonuclear leukocytes, and as a soluble protein in the blood. Its main function is to serve as a receptor for lipopolysaccharide (LPS). Besides its role in endotoxin signaling, it has been proposed that CD14 is involved in the transportation of other lipids, cell-cell interactions during different immune responses, and recognition of apoptotic cells.
CD14 is highly expressed on the surface of monocytes/macrophages and strongly up-regulated during the differentiation of monocytic precursor cells into mature monocytes. Therefore, CD14 has been commonly used as a differentiation marker for monocytes/macrophages. An antibody to CD14 also labels Langerhans cells and dendritic cells.

Composition: Anti-human CD14 rabbit monoclonal antibody purified from serum and prepared in 10mM PBS, pH 7.4, with 0.2% BSA and 0.09% sodium azide.

Name: CD19 Antibody (Clone SP110)

Description and aplications: This antibody recognizes the CD19, a surface glycoprotein of 95 kD which is present in both malignant and normal B cells which was always been considered as the most reliable surface marker of this cell line, within all range of stages of maturation. In the normal lymphoid tissue, the CD19 staining appears in germinal centers (follicular dendritic cells and B cells) in the mantle zone and as scattered cells within the interfollicular areas with overlapping patterns of immunostaining with CD20 and CD22 cells. However, in contrast to CD20, CD19 is also expressed on pre-B cells. CD19 was detected by flow cytometry in extramedullary plasma cells isolated from human tissue. CD19 positivity appears in the vast majority of B cell neoplasms while the plasma cell neoplasms are always negative. No CD19 stain was detected in Reed- Sternberg cells of Hodgkin’s disease.

Composition: anti-CD19 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.

CD1a binds self and non-self lipid and glycolipid antigens, presenting them to T-cell receptors on natural killer T-cells. CD1a antibody labels cortical thymocytes, Langerhans’ cells and dendritic cells. It has been used to identify Langerhans’ cell histiocytosis and precursor T lymphoblastic lymphoma/leukemia.

Composition: Anti-human CD1a rabbit monoclonal antibody purified from serum and prepared in 10mM PBS, pH 7.4, with 0.2% BSA and 0.09% sodium azide

Intended use: Immunohistochemistry (IHC) on paraffin embedded tissues. Not tested on frozen tissues or Western-Blotting

Immunogen: A synthetic peptide corresponding to residues in human CD1a protein.

Name: CD2 Antibody Clone EP222

Description and applications: T-cell surface antigen CD2 (CD2) is a T-cell specific surface glycoprotein that is critically important for mediating adherence of T cells to antigen-presenting cells or target cells. It interacts with lymphocyte functionassociated antigen (LFA-3) and CD48/BCM1 to mediate adhesion between T-cells and other cell types. CD2 is involved in triggering T-cells, and the cytoplasmic domain is involved in signaling. CD2 is a pan T-cell marker. CD2 antibody labels T-cell, thymocytes and natural killer (NK) cells. CD2 is absent in a small subset of T cells. CD2 antibody is useful for identification of precursor and mature T-cell lymphomas. Aberrant loss of CD2 in T-cell lymphomas may helpful to distinguish them from reactive T-cell proliferations.

Composition: Anti-human CD2 rabbit monoclonal antibody purified from serum and prepared in 10mM PBS, pH 7.4, with 0.2% BSA and 0.09% sodium azide.

Immunogen:human CD2 recombinant protein.
