Anti-IL12B antibodies are used in the immunodetection of the protein interleukin 12B. In humans, the canonical protein has a reported length of 328 amino acid residues and a mass of 37.2 kDa. It has been described to be a secreted protein. It is notably expressed in many tissues, such as the cerebral cortex, tonsil, and bone marrow. A member of the IL-12B protein family, IL12B is a reported cytokine that can act as a growth factor for activated T and NK cells, enhance the lytic activity of NK/lymphokine-activated killer cells, and stimulate the production of IFN-gamma by resting PBMC. Synonyms for this target antigen include CLMF2, IMD28, IMD29, NKSF, NKSF2, interleukin-12 subunit beta, CLMF p40, and CLMF. IL12B gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 950 citations in the literature describe the use of IL12B antibodies in research. ELISA is a widely used application for these antibodies. In addition, Western Blot is also a common application.
