CD8 FITC

Description: The SK1 monoclonal antibody reacts with the human CD8 alpha molecule, an approximately 32-34 kDa cell surface receptor expressed either as a heterodimer with the CD8 beta chain (CD8 alpha/beta) or as a homodimer (CD8 alpha/alpha). A majority of thymocytes and a subpopulation of mature T cells and NK cells express CD8 alpha. CD8 binds to MHC class I and through its association with protein tyrosine kinase p56 lck plays a role in T-cell development and activation of mature T cells.
