Matriks Biotek SHIKARI® ELISA Kits
Matriks Biotek® Co. is an innovation oriented company committed to the research and development of biological products and technologies that promote immunological health. In the 9 years since their global release, Matriks' SHIKARI® ELISA kits have come to be used by over 30 pharmaceutical industry leaders across 36 countries. 

The growing use of biologics in pharmaceutical products elicits important questions about the efficacy of such treatments and discrepancies in outcomes between individual patients. Matriks' line of SHIKARI ELISA kits allows researchers to accurately monitor drug levels present in samples and the corresponding immunogenic responses, a key diagnostic tool for explaining the success or failure of these drugs and guiding health professionals towards safer, more effective treatments.
