Product details

ProductELISpot Plus: Human IL-12/-23 p40 (HRP)
ApplicationELISpot
AnalyteIL-12/-23 (p40)
ReactivityHuman, Non-human primates
SpecificityThis kit is based on a matched pair of mAbs specific for the p40 subunit of human IL-12 and IL-23. The antibodies recognize p40 monomer and homodimer, IL-12 p70 (p40+p35), and IL-23 (p40+p19).
Cross-reactivityThe mAbs react with human IL-12/-23 (p40) and cross-react with IL-12/-23 (p40) from non-human primates (NHP). For more information please check the Cross-reactivity guide section below.

Shipping and Storage

ShippingShipped at ambient temperature.
StorageStore antibodies, enzyme conjugate, and substrate at 4-8 °C upon receipt. Plates may be kept at room temperature.
Shelf lifeAt least 18 months from date of receipt.

The systems reactive with NHPs are either based on cross-reactive human kits or specifically developed monkey kits (NHP).

Cross-reactivity verification tests have been performed in ELISpot and/or ELISA by Mabtech and/or by others. Evaluations of assays with less solid evidence of cross-reactivity are shown as symbols within parentheses.

IL-12/-23 (p40)

Analyte description

Interleukin 12 (IL-12) is, when biologically active, a heterodimer (p70) consisting of two covalently linked subunits, p35 and p40. IL-12 is produced by antigen-presenting cells, specifically dendritic cells, and macrophages. IL-12 is a proinflammatory cytokine that promotes Th1-type responses by inducing IFN-γ production and enhancing the proliferation and cytotoxicity of NK and T cells.

Interleukin-23 (IL-23) is a disulfide-linked heterodimer that consists of a unique p19 subunit and the p40 subunit of IL-12. IL-23 is a proinflammatory cytokine, which is produced by macrophages and dendritic cells upon infections with certain pathogens. The IL-23 receptor is expressed on Th17 cells, and IL-23 is responsible for Th17 expansion and stabilization.

Since both IL-12 and IL-23 heterodimers comprise the p40 subunit, capture immunoassays based on antibodies to p40 will detect both cytokines. Such assays can also detect p40 monomers and dimers.
