Human/Mouse IL-12/IL-35 p35 APC-conjugated Antibody

2 citations
  • 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.
  • Formulation
    Supplied in a saline solution containing BSA and Sodium Azide.
  • Label
  • Intracellular Staining by Flow Cytometry
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Preparation and Storage
  • Stability & Storage
    Store the unopened product at 2 - 8° C. Do not use past expiration date. Protect from light.
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).
