Mouse IL-23 alpha&IL-12 beta Heterodimer Protein, His Tag&Tag Free (MALS verified)

Interleukin-23 subunit alpha (IL-23 alpha) can associates with IL12B to form the IL-23 interleukin, a 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 a 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.

Mouse IL-23A&IL-12B Heterodimer Protein, His Tag&Tag Free, produced by co-expression of IL-23A and IL-12B, has a calculated MW of 20.5 kDa (IL-23A) and 35.8 kDa (IL-12B) . Subunit IL-23A is fused with a polyhistidine tag at the N-terminus and subunit IL-12B contains no tag. The reducing (R) protein migrates as 20 kDa (IL-23A) and 45 kDa (IL-12B) respectively due to glycosylation.

● -20°C to -70°C for 12 months in lyophilized state; ● -70°C for 3 months under sterile conditions after reconstitution. For long term storage, the product should be stored at lyophilized state at -20°C or lower.
