Description

Background

CD8a antibody reacts with the 32-34 kDa alpha subunit of mouse CD8, known as CD8a or CD8 alpha. CD8a can form a homodimer (CD8 alpha-alpha), but is more commonly expressed as a heterodimer with a second chain known as CD8b or CD8 beta. CD8 acts as a co-receptor in antigen recognition and subsequent T cell activation that is initiated upon binding of the T cell receptor (TCR) to antigen-bearing MHC Class I molecules. The cytoplasmic domains of CD8 provide binding sites for the tyrosine kinase lck, facilitating intracellular signaling events that lead to T cell activation, development, and cytotoxic effector functions. CD8+ cytotoxic T cells (CTLs) play an important role in inducing cell death of tumor cells, as well as cells infected by virus, bacteria or parasites.The 53-6.7 antibody is widely used as a phenotypic marker for mouse CD8a expression on cytotoxic T cells, thymocytes, as well as on certain cell types that do not also express the TCR, including some NK cells and lymphoid dendritic cells.

Application Note

Anti-CD8a is useful for Immunohistochemistry, Immunoprecipitation, and Flow Cytometry using mouse spleen cells, or an appropriate cell type (where indicated). Researchers should determine optimal titers for applications that are not stated.

Purity/Specificity

Fluorescein conjugated CD8a Monoclonal Antibody was purified from tissue culture supernatant via affinity chromatography and is directed against mouse CD8a. Cross reactivity with CD8a from other sources has not been tested. Anti-CD8a is conjugated with FITC under optimal conditions and the solution is free of unconjugated FITC.

Storage Condition

Store vial at 4° C prior to opening.  This product is stable for several weeks at 4° C as an undiluted liquid.  Dilute only prior to immediate use.  DO NOT FREEZE. This product is light sensitive.
