Mouse anti Human CD8 antibody, clone 4B11 recognizes the human CD8 cell surface antigen, a ~32 kDa glycoprotein expressed by the cytotoxic/suppressor subset of T-cells and weakly by NK cells. Mouse anti Human CD8 antibody, clone 4B11 was raised based on an earlier successful strategy used to generate rabbit polyclonal antibodies against human CD8 employing the same immunizing peptide (Mason et al. 1992).

Mouse anti Human CD8 antibody, clone 4B11 has been reported as being suitable for use in Western blotting (Williamson et al. 1998) .

Product Details

Target Species
Product Form
Tissue Culture Supernatant - liquid
Preservative Stabilisers
0.09%Sodium Azide
Synthetic peptide derived from the carboxy terminal region of the human CD8 alpha chain coupled to a N-terminal cysteine, with the sequence C-KSDGKPSLSARYV. The peptide was coupled to bovine serum albumin and keyhole limpet hemocyanin.
Fusion Partners
Spleen cells from immunised mice were fused with cells of a mouse p3-NS1-Ag4-1 myeloma cell line.
