IL-12 beta Protein, also known as natural killer cell stimulatory factor 2, is a common subunit (p40) of IL-12 and IL-23. IL-12 is a inflammatory factor expressed by activated macrophages, and involves in Th1-type immune response against cancer [1] . IL-12 beta Protein located outside the cell membrane, involves in singalling mediated by Jak-STAT [3] . IL-12 beta Protein consists of 328 amino acids (M1-S328) with a fibronectin type-III domain (237-328 a.a). IL-12 beta Protein, Human (M1-S328) is produced in HEK293 cells with a C-Terminal Fc-tag.

Human

IL-12 beta Protein, as known as IL12 p40 subunit or IL-12B, heterodimerizes with the IL-12 p35 subunit (IL-12A) to form IL-12 and with the IL23 p19 subunit to form IL-23, exerting different regulating functions [1] . IL-12 and IL23 belong to IL-12 family, are involved in proinflammatory responses and expressed by activated macrophages that serve as an essential inducer of Th1 cells development [2] . IL-12 signals via IL-12Rβ1 and IL-12Rβ2 mediated by p-STAT4, whereas IL-23 signals via IL-12Rβ1 and IL-23R mediated by p-STAT1 and p-STAT3 [3] . The sequence of amino acids in IL-12 beta proteins of human is very different from mouse (69.04%) and rat (69.04%). Interleukin 12 (IL-12) family have been known to be inflammatory factors, induce autoimmune inflammation and thus may be responsible for autoimmune inflammatory diseases and may be important for tumorigenesis [4] .
