The CD8, clone 3B5, Pacific Blue™ dye conjugate is a monoclonal mouse antibody that recognizes the CD8 antigen also known as T8 and Lyt2,3. Our Pacific Blue™ dye is optimally excited by the violet laser and conjugates of this dye are strongly fluorescent even at neutral pH. Pacific Blue™ and Pacific Orange™ dye conjugates can be simultaneously excited at 405 nm and emit at 455 nm and 551 nm, respectively, facilitating two-color analysis.


Specificity for CD8
This antibody recognizes the CD8 antigen also known as T8 and Lyt2,3.This antibody recognizes the α-chain alone as well as the αβ heterodimer. CD8 serves as a coreceptor during T-cell activation through the binding of MHC Class I molecules. CD8 is expressed on thymocyte subsets and cytotoxic T cells.
