IL12B (Interleukin-12 Subunit beta, IL-12B, Cytotoxic Lymphocyte Maturation Factor 40kD Subunit, CLMF p40, IL-12 Subunit p40, NK Cell Stimulatory Factor Chain 2, NKSF2)
Description:
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. Associates with IL23A to form the IL-23 interleukin, an heterodimeric cytokine which functions in innate and adaptive immunity. IL-23 may constitute with IL-17 an acute response to infection in peripheral tissues. IL-23 binds to an heterodimeric receptor complex composed of IL12RB1 and IL23R, activates the Jak-Stat signaling cascade, stimulates memory rather than naive T-cells and promotes production of proinflammatory cytokines. IL-23 induces autoimmune inflammation and thus may be responsible for autoimmune inflammatory diseases and may be important for tumorigenesis.

Applications:
Suitable for use in ELISA, Western Blot and Immunohistochemistry. Other applications not tested.

Recommended Dilution:
ELISA: 1:16,000
Western Blot: 0.1-0.3ug/ml, observed in human liver lysates on ~37kD bands
Immunohistochemistry (Paraffin): 4-6ug/ml
Optimal dilutions to be determined by the researcher.
