Biochem/physiol Actions

CD8a (Cluster of Differentiation 8a) is a human gene. CD8 bind to class I MHC and the co-receptors during the process of cytotoxic T-cell activation. T cells that express T cell receptor (TCR) complexes, which lack CD3 δ, exhibit severely impaired positive selection and TCR-mediated activation of CD8 single-positive T cells. CD3 δ couples with TCR. The CD3 associated with CD8 is required for effective activation and positive selection of CD8⁺ T cells. CD8 expression is a recurrent rare phenomenon in patients with chronic lymphocytic leukemia (CLL).

Recognizes the CD8 human T cytotoxic/suppressor lymphocyte cell surface glycoprotein. Approximately 90% of thymocytes are stained in suspension. In thymus sections, both cortical and medullary thymocytes are stained. A subset of NK cells express this antigen weakly. The epitope recognized by this clone is sensitive to routine formalin fixation and paraffin embedding.

General description

CD8 is a two chain complex (α/α, α/β) receptor for Class I MHC molecules. The receptor′s cytoplasmic portion is associated with p56^lck protein tyrosine kinase which phosphorylates nearby proteins. The antigen is strongly expressed on approximately one third of mature T cells (cytotoxic/suppressor T cells).

Monoclonal Anti-Human CD8 (mouse IgG2a isotype) is derived from the hybridoma produced by the fusion of mouse myeloma cell line NS-1 and splenocytes from Balb/c mice immunized with human thymocytes followed by peripheral blood T cells. The CD8 antigen is strongly expressed on approximately one-third of mature T cells (cytotoxic/suppressor T cells). Monoclonal Anti-CD8 does not stain B lymphocytes, monocytes, or granulocytes.

Immunogen

human thymocytes followed by peripheral blood T cells.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 15 mM sodium azide.

Preparation Note

Prepared by conjugation to fluorescein isothiocyanate isomer I (FITC). This green dye is efficiently excited at 495 nm and emits at 525 nm.
