Active Recombinant Human IL12A Protein (Arg23-Ser219), C-His tagged, Animal-free, Carrier-free

• Cat.No.: IL12A-176H
• Product Overview: Recombinant Human IL12A Protein (Arg23-Ser219) with C-His tag was expressed in E. coli and Animal-free as well as Carrier-free.

Specification

• Description: Interleukin 12 (IL-12) is a pro-inflammatory cytokine with a molecular weight of 70 kDa composed of two subunits, IL-12p35 (35 kDa) and IL-12p40 (40 kDa), and IL-12p35 as a p35-p35 homodimer with 57 kDa molecular weight and a p35 monomer of 27 kDa molecular weight. The p35 molecule is unique to IL-12, while p40 is shared by both IL-12 and IL-23. IL-12 promotes Th1 T cell responses, while IL-23 promotes Th17 T cell responses.
