Recombinant Human Interleukin 12B, Fc-Tagged

Cat. No.: IL12B-35H
Product Overview: Recombinant Human Interleukin 12B, Fc-Tagged expressed in E.coli is a disulfide-linked homodimer. The reduced monomer consists of 544 amino acids and has a predicted molecular mass of 61.4 kDa. As a result of glycosylation, the rhIL12B/Fc monomer migrates as an approximately 70-80 kDa band in SDS-PAGE under reducing conditions.
Description: Interleukin 12, a cytokine that acts on T and natural killer cells, and has a broad array of biological activities. Interleukin 12 is a disulfide-linked heterodimer composed of the 40 kD cytokine receptor like subunit encoded by this gene, and a 35 kD subunit encoded by IL12A. This cytokine is expressed by activated macrophages that serve as an essential inducer of Th1 cells development. This cytokine has been found to be important for sustaining a sufficient number of memory/effector Th1 cells to mediate long-term protection to an intracellular pathogen. Overexpression of this gene was observed in the central nervous system of patients with multiple sclerosis (MS), suggesting a role of this cytokine in the pathogenesis of the disease. A DNA sequence encoding the p40 subunit of human IL12, termed asIL12B (NP_002178.2) (Met 1- Ser 328 ) was fused with the Fc region ofhuman IgG1 at the C-terminus.
