cFluor® V420 anti-Human CD8 (SK1)
View Cart or Continue shopping.
The SK1 monoclonal antibody binds to human CD8a, a 32-34-kDa type I glycoprotein that forms either as an α/α homodimer α/β heterodimer with its isoform CD8b. CD8 is found on thymocytes, a subset of peripheral blood T cells, majority expressing α/β heterodimer, and NK cells, majority expressing α/α homodimer1. CD8 plays a role in antigen recognition and class I MHC-restricted T cell development. CD8 functions are associated with two domains of CD8a. CD8a ectodomain binding to the α3 domain of MHC class I increases the adhesion between CD8+ T lymphocytes and target cells. The cytoplasmic tail binding to the tyrosine kinase p56lck contributes to signal transduction and T cell activation2,3. The antibody was conjugated to a fluorophore and puriﬁed by afﬁnity chromatography.

Each lot of this antibody is quality control tested using flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 5 µL per 1 million cells in a staining volume of 100 µL. If whole blood is analyzed, then use 5 µL per 100 µL. It is recommended that users titrate the antibody to obtain the optimal result for their specific application.
Please briefly centrifuge the reagent vial before use.
