S. frugiperda insect ovarian cell line Sf 21-derived recombinant human IL‑12/IL-35 p35 Arg23-Ser219 Accession # P29459
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.

p35
is a 34-36 kDa monomeric member of the IL-6 superfamily of molecules. It is 219 amino acids in length, and possibly
contains an N-terminal 22 aa signal sequence.
In any event, it does not appear to be individually secreted, and its
release from cells is commonly assumed to be as part of a disulfide-linked
heterodimer linked to either p40 (forming IL-12) or EBI3 (forming IL-35). Multiple cell types are known to express p35,
and include keratinocytes, CD138+ plasma cells, naïve B cells, monocyte-derived
dendritic cells, macrophages, CD86lo B7-H1hi CD206+
B7-DC+ tolerogenic dendritic cells, neutrophils, activated monocytes and
macrophages, trophoblasts, testicular endothelial cells, and T cells, including
CD4+ and CD8+ T helper cells, and CD4+ CD25+ Tregs. The presence of the subunit does not
necessarily indicate function, as the p35:p40 heterodimer is associated with
promoting inflammatory IFN-gamma production by NK cells, while the p35:EBI3
heterodimer is anti-inflammatory through its inhibition of Th17 cell
development. Over aa 23-219, human p35
shares 83% and 57% aa sequence identity with pig and mouse p35, respectively.
