Background :
RIV11 is a mouse monoclonal IgG1 antibody derived by fusion of 653 mouse myeloma cells with splenocytes from a BALB/c mouse immunized with human peripheral blood lymphocytes.

Source :
CD8 is a 32kDa cell surface transmembrane glycoprotein expressed by most thymocytes, a subpopulation of mature peripheral blood T-cells and natural killer (NK) cells. CD8 is expressed on the cell surface as a heterodimer, comprising two distinct disulphide linked α and β polypeptide chains, or as a CD8α homodimer. The CD8 αβ heterodimer is expressed on T-cell receptor (TCR) αβ+ cytotoxic T-lymphocytes (CTL’s), whereas CD8α homodimers are expressed on TCR γδ+ T-cells, natural killer cells and a subpopulation of TCR αβ+ T-cells. The CD8 molecule functions as a co-receptor (with the T-cell receptor) as part of the antigen-recognition complex on TCRαβ+, class I MHC-restricted T cells and plays an important role in T-cell signaling. The CD8 Ig-like domain binds to the alpha-3 domain of MHC-Class 1. <

Product :
Each vial contains 500 µl 0.2 mg/ml purified monoclonal antibody in phosphated buffered saline (PBS) containing 50% glycerol + 0.2% bovine serum albumin (BSA) + 0.02% sodium azide. Formulation: Each vial contains 500 µl 0.2 mg/ml purified monoclonal antibody in phosphated buffered saline (PBS) containing 50% glycerol + 0.2% bovine serum albumin (BSA) + 0.02% sodium azide.

Specificity :
The antibody RIV11 is directed against human CD8 and recognises all CD8 positive T-cells, thymocytes and natural killer cells.

Applications :
The RIV11 antibody is suitable for the detection of total CD8 by flow cytometry and ELISA. The antibody is also suitable for the detection of CD8 by immunocytochemistry and immunohistochemistry on frozen tissues. Human lymph node, spleen and peripheral blood lymphocytes are suitable for use as positive controls. Optimal antibody dilutions for the different applications should be determined by titration.

Storage :
The antibody is shipped at ambient temperature and may be stored at +4°C. For prolonged storage prepare appropriate aliquots and store at or below -20°C. Prior to use, an aliquot is thawed slowly in the dark at ambient temperature, spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. Working dilutions should be stored at +4°C, not refrozen, and preferably used the same day. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance or the concentration of the product.

Antibodies are immunoglobulins secreted by effector lymphoid B cells into the bloodstream. Antibodies consist of two light peptide chains and two heavy peptide chains that are linked to each other by disulfide bonds to form a “Y” shaped structure. Both tips of the “Y” structure contain binding sites for a specific antigen. Antibodies are commonly used in medical research, pharmacological research, laboratory research, and health and epidemiological research. They play an important role in hot research areas such as targeted drug development, in vitro diagnostic assays, characterization of signaling pathways, detection of protein expression levels, and identification of candidate biomarkers.
