Human/Mouse IL-12/IL-35 p35 PerCP-conjugated Antibody Summary

Species Reactivity

Human, Mouse

Specificity

Detects human IL‑12/IL-35 p35 in direct ELISAs and Western blots. Detects the p35 subunit either as part of a p40/p35 heterodimer or as a free subunit after reduction of the heterodimer. This antibody does not recognize IL-12 p40 homodimers but shows strong cross-reactivity with the p35 subunits from porcine and mouse systems.

Detection of IL‑12/IL‑35 p35 in Human PBMCs by Flow Cytometry. Human peripheral blood mononuclear cells (PBMCs) either untreated (light orange filled histogram) or treated with LPS (dark orange filled histogram) were stained with Mouse Anti-Human/Mouse IL-12/IL-35 p35 PerCP-conjugated Monoclonal Antibody (Catalog # IC2191C) or isotype control antibody (Catalog # IC002C, open histogram). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (Catalog # FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (Catalog # FC005).

Background: IL-12/IL-35 p35

Interleukin 12 (IL-12) and interleukin 35 (IL-35) are heterodimeric cytokines composed of alpha and beta chains. IL-12 is composed of p35 and p40 subunits, while IL-35 is comprised of p35 paired with EBI-3 (1). In mice, IL-35 is produced by FoxP3⁺ regulatory T cells and may function as an inhibitory cytokine to suppress T cell proliferation (2). Human FoxP3⁺ Tregs do not constitutively express IL-35 (3), but expression may be induced by activated dendritic cells (4).
