Recombinant HumanT-cell-specific surface glycoprotein CD28 (NP_001230006.1) (19-152 aa) was expressed in Mammalian cell with a hFc-tag at the C-terminus. The biological activity was determined by its binding ability in a functional ELISA. This product can be used in ELISA, WB, and IP.
Biological Activity
Determined by its binding ability in a functional ELISA.
Involved in T-cell activation, the induction of cell proliferation and cytokine production and promotion of T-cell survival. Enhances the production of IL4 and IL10 in T-cells in conjunction with TCR/CD3 ligation and CD40L costimulation.
