Description

Description

IL-23 is a heterodimeric cytokine composed of the p40 subunit of IL-12 disulfide-linked with a protein p19. p19, like p35 of IL-12, is biologically inactive by itself. IL-23 interacts with IL-12Rbeta1 and an additional, novel beta2-like receptor subunit with STAT4 binding domain, termed IL-23R. IL-23 is secreted by activated mouse and human dendritic cells. Biological activities of mouse IL-23 are distinct from those of mouse IL-12. Mouse IL-23 was found not to induce significant amounts of IFN-γ. Mouse IL-23 does induce strong proliferation of memory T cells (but not naive T cells), whereas IL-12 has no effect on memory cells. Additionally, mouse IL-23 (but not IL-12) can activate mouse memory T cells to produce the proinflammatory cytokine IL-17. Human IL-23 has biological properties which are less distinct from human IL-12; human IL-23 induces proliferation of memory T cells and induces moderate levels of IFN-γ production by naive and memory T cells, as compared to IL-12.

Applications Reported: Mouse IL-23 Recombinant Protein Carrier-Free has been reported for use in cytokine bioassays. Applications Tested: The ED50 of this protein, as measured by IL-17A induction in mouse splenocytes, is less than or equal to 625 pg/mL. This corresponds to a specific activity of greater than 1.5 x 10e6 Units/mg. Source: Insect cells infected with baculovirus: mouse p40, amino acids met 1-Ser 355, accession &Num; NM_008352 was co-expressed with mouse p19, amino acids met 1-Ala 196, accession &Num; AF301619. Bioactivity: The ED50 of this protein, as measured by IL-17A induction in mouse splenocytes, is less than or equal to 625 pg/mL. This corresponds to a specific activity of greater than 1.5 x 10e6 Units/mg. Endotoxin: Less than 0.01ng/ug cytokine as determined by the LAL assay. Purity: >98% as determined by SDS-PAGE. Molecular Weight: The heterodimer of p40, amino acids met 23-ser 355, cystine-linked to p19, amino acids leu 20-ala 196, has a predicted molecular mass of 55,616. On non-reducing SDS-PAGE the heterodimeric cystine-linked protein migrates as a 60 kDa protein. The DTT reduced protein migrates as 43 kDa and 21 kDa polypeptides. Storage and handling: For best recovery, quick-spin vial prior to opening. Use in a sterile environment.
