IL-23 alpha Protein, Human (HEK293, Fc)

Cat. No.: HY-P76432
COA Handling Instructions

IL-23, collaborating with IL12B, constitutes the pro-inflammatory cytokine IL-23, crucial in innate and adaptive immunity. Released by antigen-presenting cells like dendritic cells or macrophages, IL-23 binds to IL12RB1 and IL23R, activating JAK2 and TYK2. This cascade phosphorylates STAT3 and STAT4, activating pathways like p38 MAPK or NF-kappa-B, inducing pro-inflammatory cytokines. IL-23 contributes to intracellular bacterial clearance and supports the expansion of T-helper 17 cells, including IL-17 producers. The disulfide-linked IL-23 interacts with IL12B and IL23R, recruiting IL12RB1. IL-23 alpha Protein, Human (HEK293, Fc) is the recombinant human-derived IL-23 alpha protein, expressed by HEK293, with C-hFc labeled tag. The total length of IL-23 alpha Protein, Human (HEK293, Fc) is 170 a.a., with molecular weight of ~45.4 KDa.

Background

IL-23, in collaboration with IL12B, forms the pro-inflammatory cytokine IL-23, playing diverse roles in both innate and adaptive immunity. Released by antigen-presenting cells such as dendritic cells or macrophages, IL-23 binds to a heterodimeric receptor complex comprising IL12RB1 and IL23R, initiating a cascade involving JAK2 and TYK2 activation. These kinases phosphorylate the receptor, creating a docking site for the subsequent phosphorylation of STAT3 and STAT4. This process activates multiple pathways, including p38 MAPK or NF-kappa-B, fostering the production of pro-inflammatory cytokines, such as interleukin-17A/IL17A. Additionally, IL-23 actively participates in the early and effective clearance of intracellular bacteria. Notably, IL-23 promotes the expansion and survival of T-helper 17 cells, a CD4-positive helper T-cell subset known for producing IL-17, alongside other IL-17-producing cells. The heterodimeric association of IL-23 with IL12B, known as interleukin IL-23, is disulfide-linked. Furthermore, IL-23 interacts with IL23R, facilitating the recruitment of IL12RB1.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
