  Neutralization experiment of NeutraKine® IL-23 p40 using 69006-1-Ig

  Recombinant human IL-23 (Cat.NO. HZ-1254) induces invitro cultured mouse splenocytes to secret IL-17A in a dose-dependent manner (blue curve, refer to bottom X-left Y). The activity of human IL-23 (4 ng/mL HZ-1254) is neutralized by mouse anti-human IL-23 p40 monoclonal antibody 69006-1-Ig at serial dose (red curve, refer to top X-right Y). The ND50 is typically 8-30 ng/mL.

  Neutralization experiment of NeutraKine® IL-23 p40 using 69006-1-Ig

  Recombinant human IL-23 (Cat.NO. HZ-1254) induces in vitro cultured mouse splenocytes to secret IL-17A in a dose-dependent manner (blue curve, refer to bottom X-left Y axis). The activity of human IL-23 (4 ng/mL HZ-1254) is neutralized by mouse anti-human IL-23 p40 monoclonal antibody 69006-1-Ig at serial dose (red curve, refer to top X-right Y). The ND50 is typically 8-30 ng/mL. The NeutraControl mouse anti-human IL-23 p40 monoclonal antibody 69506-1-Ig could recognize human IL-23, but could not neutralize human IL-23 in the range of 0.244-4000ng/mL(green curve, refer to top X-right Y axis).

  ELISA experiment of Recombinant protein using 69006-1-Ig

  Indirect ELISA was carried out by coating recombinant Human IL-23 (Cat.NO. HZ-1254) at 70 ng/well followed by blocking and adding serial diluted IL-23 antibody 69006-1-Ig and 69506-1-Ig respectively. Signal was developed with TMB and stopped by H2SO4. Signal strength was measured by absorbance at 450 nm.

  ELISA experiment of Recombinant protein using 69006-1-Ig

  Indirect ELISA was carried out by coating recombinant Human IL-12 (Cat.NO. HZ-1256) and IL-12 p40 (Cat.NO. HZ-1321) respectively at 70 ng/well followed by blocking and adding serial diluted 69029-1-Ig, 69529-1-Ig and 69006-1-Ig respectively. HRP-goat anti-mouse was used for detection. Signal was developed with TMB and stopped by H2SO4. Signal strength was measured by absorbance at 450 nm. The result suggests that 69029-1-Ig and 69529-1-Ig only recognize IL-12(p35 and p40 heterodimer) but not recognize IL-12/IL-23 p40.

Background Information

IL-12 and IL-23 are heterodimeric cytokines that share a common p40 subunit (PMID: 11114383). IL-12 is composed of the IL-12 p40 subunit linked to the IL-12 p35 subunit, and the heterodimer signals through the IL-12 receptor (IL-12R), which comprises the IL-12Rβ1 and IL-12Rβ2 subunits. IL-23 is composed of the IL-23 p19 subunit and the IL-12 p40 (IL-12/23p40) subunit, which signals through IL-23R and IL-12Rβ1 (PMID: 11114383; 26121196 ). IL-12/IL-23 p40 also exists as a monomer and as a homodimer which can act as a potent IL-12 antagonist (PMID: 8958912; 18783467). IL-12/IL-23 p40 is produced by antigen-presenting cells, such as dendritic cells (DCs), monocytes, macrophages, neutrophils and, to a lesser extent, B cells (PMID: 20476918).

This antibody can be used to neutralize the bioactivity of IL-12/IL-23 p40.
