IL-23 alpha & IL-12 beta
Cynomolgus IL-23A & Mouse IL-12B Heterodimer Protein, His Tag&Tag Free (ILB-CM52W8) is expressed from human 293 cells (HEK293). It contains AA Val 22 - Pro 189 (IL23A) & Met 23 - Ser 335 (IL12B) (Accession # A0A2K5TLV4-1 (IL23A) & P43432-1 (IL12B)).
Predicted N-terminus: His (IL23A) & Met 23 (IL12B)
Cynomolgus IL-23A & Mouse IL-12B Heterodimer Protein, His Tag&Tag Free, produced by co-expression of IL-23 alpha and IL-12 beta, has a calculated MW of 20.3 kDa (IL-23 alpha) and 35.8 kDa (IL-12 beta). Subunit IL-23 alpha is fused with a polyhistidine tag at the N-terminus and subunit IL-12 beta contains no tag. The reducing (R) protein migrates as 20-23 kDa (IL-23 alpha) and 40-42 kDa and 43-46 kDa (IL-12 beta) respectively due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>90% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

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.
