描述(Description)
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.
純度(Purity)
≥95%, by SDS-PAGE (under reducing (R) & Non-reducing conditions, visualized by Coomassie staining)
生物活性(Bioactivity)
Measured by its ability to induce Interferon gamma secretion by human natural killer lymphoma NK-92 cells. The ED50 for this effect is <0.5 ng/mL.
