Human IL-12/IL-23 p40 Antibody Summary

Species Reactivity
Human
Specificity
Detects human IL-12/IL-23 p40 in ELISAs. In ELISAs, this antibody shows less than 5% cross-reactivity with recombinant human (rh) IL‑12 (p35/p40 heterodimer) and rhIL-23 (p19/p40 heterodimer). No significant cross-reactivity or interference was observed with rhIL-1 alpha, rmIL-1 alpha, rhIL-1 beta, rmIL-1 beta, rhIL-1ra, rhIL-1 RI, rhIL-1 RII, rhIL-2, rhIL-2 R alpha, rhIL-3, rmIL-3, rhIL-4, rmIL-4, rhIL-4 R, rhIL-5, rmIL-5, rhIL-5 R beta, rhIL-6, rhIL-6 R, rmIL-6, rhIL-7, rmIL-7, rhIL-8, rhIL-9, rmIL-9, rhIL-10, rmIL-10, rhIL-11, rmIL-12, rmIL-12 p40, rhIL-13, or rmIL-13.

Background: IL-12/IL-23 p40

Interleukin 12, also known as natural killer cell stimulatory factor (NKSF) or cytotoxic lymphocyte maturation factor (CLMF), is a pleiotropic cytokine originally identified in the medium of activated human B lymphoblastoid cell lines. IL-12 is produced by macrophages and B lymphocytes and has multiple effects on T-cells and NK cells, including stimulation of cytotoxic activity, proliferation, and promotion of Th1 development as well as IFN-gamma and TNF production. IL-12 is a
disulfide-linked, 70 kDa (p70) heterodimeric glycoprotein composed of a 40 kDA (p40) subunit and a 35 kDa (p35) subunit. The p40 and p35 subunits by themselves have no IL‑12 activity, the p40 dimer has been shown to bind the IL-12 receptor and to be an IL-12 antagonist. Free p35 has not been detected in supernatant solutions of cultured cells expressing only p35 or both p35 and p40 mRNAs. In contrast, p40 is secreted in excess of IL-12 in cells expressing both p35 and p40 mRNAs. The p40 subunit of IL-12 has been shown to have extensive amino acid sequence homology to the extracellular domain of the human IL-6 receptor while the p35 subunit shows distant but significant sequence similarity to IL-6, G-CSF, and chicken MGF. These observations have led to the suggestion that IL-12 might have evolved from a cytokine/soluble receptor complex. Human and mouse IL-12 share 70% and 60% amino acid sequence homology in their p40 and p35 subunits, respectively. IL-12 apparently shows species specificity with human IL-12 reportedly showing minimal activity in the murine system.
