CD6, also known as T-cell differentiation antigen CD6, is a member of the group B SRCR (scavenger receptor cysteine-rich) superfamily. CD6 is a cell surface glycoprotein expressed primarily on T cells and It expressed by thymocytes, mature T-cells, a subset of B-cells known as B-1 cells, and by some cells in the brain. And T-cell differentiation antigen CD6 appears to play a role as both a co-stimulatory molecule in T cell activation and as an adhesion receptor. CD6 binds to CD166(known as ALCAM), and is considered as a costimulatory molecule involved in lymphocyte activation and thymocyte development.. Certain alleles of this protein may be associated with susceptibility to multiple sclerosis. Recombinant protein corresponding to aa18-402 from human CD6, fused to hIgG-His-Tag at C-terminal, expressed in Baculovirus. Molecular Weight: ~68.3kD Biological Activity: Measured by the ability of the immobilized protein to support the adhesion of Jurkat human acute T cell leukemia cells. When cells are added to human CD6 coated plates 10ug/ml. This effect is more to 50%.
