CD8a (clone SK1) is a mouse monoclonal antibody that recognizes the human protein CD8. CD8a is a common marker of cytotoxic (Killer) T cells, and is a T cell coreceptor. All conjugates have been validated in flow cytometry. Offered in two sizes: 125uL (25 tests) or 500uL (100 tests). These antibodies belong to the Biotium Choice list of select antibodies that have been validated and optimized in-house for optimal performance. • 405 nm-excitable green fluorescent CF®405L dye has excitation/emission at 395/545 nm. • Blue fluorescent CF®405M dye has excitation/emission at 408/452 nm. • Blue fluorescent CF®405S dye has excitation/emission at 404/431 nm. • Green fluorescent CF®488A dye has excitation/emission at 490/515 nm. • Green fluorescent CF®503R dye has excitation/emission at 503/532 nm. • Green fluorescent CF®514 dye has excitation/emission at 516/548 nm. • Red fluorescent CF®568 dye has excitation/emission at 562/583 nm. • Red fluorescent CF®575 dye has excitation/emission at 575/601 nm. • Far-red fluorescent CF®647Plus dye has excitation/emission at 652/668 nm. • Far-red fluorescent CF®660C dye has excitation/emission at 667/685 nm. • Near-infrared CF®700 dye has excitation/emission at 695/720 nm. • Near-infrared APC-Astral™813 Conjugate dye has excitation/emission at 788/813 nm. • Far-red fluorescent RPE-Astral™616 dye has excitation/emission at 565/617 nm.
