The CD8, clone 3B5, Qdot® 800 nanocrystal conjugate is a mouse monoclonal antibody (mAb) that recognizes the human CD8 antigen also known as T8 and Lyt2,3. The Qdot® 800 nanocrystal conjugate may be used in the same way as conventional antibody conjugates and is most often used with 405 nm excitation, permitting simultaneous multicolor labeling of multiple targets off the violet laser. Alternatively, the nanocrystal can be excited by any laser up to the wavelength at which it absorbs.


Specificity for CD8
This antibody recognizes the CD8 antigen, also known as T8 and Lyt2,3. The antibody specifically recognizes the α-chain alone, as well as the αβ heterodimer. During T-cell activation, CD8 is a co-receptor for the T-cell receptor (TCR) by binding MHC Class I molecules. CD8 is expressed on cytotoxic T-cells and subsetsof thymocytes.
