IL-12/IL-23 p40 Monoclonal Antibody (C8.6), eBioscience™, Invitrogen™

Description

Description: The C8.6 antibody reacts with the p40 subunit of human IL-12 p70 and human IL-23. IL-12 is a 70 kDa heterodimeric cytokine composed of two covalently linked chains, p40 and p35, and secreted primarily by activated monocytes, macrophages, and dendritic cells. IL-23 is a biologically-related, heterodimeric cytokine composed of disulfide-linked p40 and p19 subunits. Applications Reported: Unlabeled C8.6 has been reported for use as a cold mAb control to block fluorochrome conjugated C8.6 in staining of intracellular IL-12 and in immunblotting under nonreducing conditions. C8.6 has also been reported for use in cytokine neutralization. (Please use Functional Grade purified C8.6, cat. 16-7129, in functional assays.). Applications Tested: The unconjugated C8.6 antibody has been tested as a cold mAb control to block fluorochrome conjugated C8.6 in staining of intracellular IL-12 and nonreducing immunoblots at 2 μg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Purity: Greater than 90%, as determined by SDS-PAGE. Aggregation: Less than 10%, as determined by HPLC. Filtration: 0.2 μm post-manufacturing filtered.

IL-12 is an interleukin produced by dendritic cells, neutrophils, macrophages and human lymphoblastoid cells as a result of antigenic stimulation. IL-12 is a heterodimeric cytokine encoded by IL-12A (p35) and IL-12B (p40). IL-23 is a heterodimeric cytokine that shares a subunit with IL-12 (IL-12B) along with an IL-23A (IL-23p19) subunit. Functionally, IL-12 increases the expression of vascular endothelial adhesion molecule-1 on the endothelium, directs leukocytes towards tumors and facilitates the ischemic-hemorrhagic necrosis of the tumor tissue. In comparison, IL-23 plays an important role in stimulating memory T-cells, and is required for the induction, expansion, maintenance and downstream effector functions of Th17 cells, which play a vital role in upregulating neutrophil chemokines and various pro-inflammatory cytokines.
