Shikari® (QS-RIS) Risankizumab ELISA (mAb-Based)

SHIKARI® Risankizumab ELISA has been especially developed for the specific and quantitative analysis of free risankizumab in serum and plasma samples. 
SHIKARI® Risankizumab Specific ELISA is optimized with Skyrizi® and biosimilars. For research use only (RUO).


Risankizumab is a humanized monoclonal antibody that specifically binds to the p19 subunit of interleukin-23 (IL-23), thereby inhibiting IL-23-mediated inflammatory signaling. Quantification of circulating free risankizumab may be useful in pharmacokinetic, immunogenicity, and biologic drug monitoring research. This assay utilizes highly specific anti-idiotypic monoclonal antibodies to selectively detect free risankizumab molecules capable of target binding. The kit is intended for the quantitative determination of free risankizumab in biological samples for research use only.

All SHIKARI® ELISA kits are suitable for biosimilar work.
All SHIKARI® ELISA kits are produced under ISO 13485 quality system.
