IL-12/IL-35 p35 Antibody (27537) [Phycoerythrin] Summary

S. frugiperda insect ovarian cell line Sf 21-derived recombinant human IL‑12/IL-35 p35
Accession # P29459
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.
Protein A or G purified from ascites

Alternate Names for IL-12/IL-35 p35 Antibody (27537) [Phycoerythrin]

  • IL-12/IL-35 p35
  • IL-12A
  • IL35p35


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).
