Product Specific Information

Description: The 5B2 antibody reacts with the p19 subunit of mouse IL-23. The 5B2 antibody in combination with the C17.8 antibody yields an improved IL-23 sandwich ELISA with greater sensitivity than was achievable with previous assays. The 5B2 antibody is a non-neutralizing antibody.

IL-23 is a heterodimeric cytokine composed of the p40 subunit of IL-12 disulfide-linked with a protein p19. p19, like p35 of IL-12, is biologically inactive by itself. IL-23 interacts with IL-12Rbeta1 and an additional, novel beta2-like receptor subunit with STAT4 binding domain, termed IL-23R. IL-23 is secreted by activated mouse and human dendritic cells. Biological activities of mouse IL-23 are distinct from those of mouse IL-12. Mouse IL-23 was found not to induce significant amounts of IFN gamma. Mouse IL-23 does induce strong proliferation of memory T cells (but not naive T cells), whereas IL-12 has no effect on memory cells. Additionally, mouse IL-23 (but not IL-12) can activate mouse memory T cells to produce the proinflammatory cytokine IL-17. Human IL-23 has biological properties which are less distinct from human IL-12; human IL-23 induces proliferation of memory T cells and induces moderate levels of IFN gamma production by naive and memory T cells, as compared to IL-12.

Applications Reported: The anti-mouse p19 5B2 antibody has been reported for use as the capture antibody for a mouse IL-23 sandwich ELISA, when used in conjunction with the anti-p40 C17.8 antibody as the detector.

Applications Tested: The 5B2 antibody has been tested as the capture antibody in a sandwich ELISA for analysis of mouse IL-23 (p19/p40) protein levels in combination with the biotinylated (p40-specific) C17.8 antibody (Product # 13-7123-81) for detection and recombinant mouse IL-23 (Product # 14-8231-63) as the standard. A suitable range of concentrations of this antibody for ELISA capture is 1-4 µg/mL. A standard curve consisting of doubling dilutions of the recombinant standard over the range of 1000 pg/mL - 8 pg/mL should be included in each ELISA plate.

For specific neutralization of mouse IL-23 protein activity (with no effect on IL-12 p70), the functional grade purified G23-8 antibody is recommended (Product # 16-7232-81) .

Purity: Greater than 90%, as determined by SDS-PAGE.

Aggregation: Less than 10%, as determined by HPLC.

Filtration: 0.2 µm post-manufacturing filtered.
