• Cat.No.: Il23A-23H
• Product Overview: Recombinant Human Il23A(Arg 20 - Pro 189)&IL12B(Ile 23 - Ser 328 ), Subunit IL-23 alpha is fused with his-tag at the N-terminus and subunit IL-12 beta contains no tag was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: Il23A(Arg 20 - Pro 189)&IL12B(Ile 23 - Ser 328 )
• Description: 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.
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
• Molecular Mass: The protein has a calculated MW of 19.5 kDa (IL23A) & 34.7 kDa (IL12B). The protein migrates as 20 kDa (IL23A) & 40-45 kDa (IL12B) on a SDS-PAGE gel under reducing (R) condition due to glycosylation.
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >95% as determined by SDS-PAGE.
• Storage: For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.
  Please avoid repeated freeze-thaw cycles.
  No activity loss is observed after storage at:
  4-8 centigrade for 12 months in lyophilized state;
  -70 centigrade for 3 months under sterile conditions after reconstitution.
