Irritection® Assay System

This advanced technology system allows you to get your new products to market faster (1-3 months faster) at half (or less) the cost, with a potentially distinguished marketing profile. Ocular Irritection® is the only 100% non-animal ocular test adopted by OECD (TG496). We offer a variety of applications which help meet GHS requirements where these assays assess ocular and/or dermal irritation. The Irritection® Assay System utilizes an automated plate reader, for speed and throughput, and customized Windows software, for automatic transfer and analysis of data, thus providing accurate and reproducible results in as few as 24 hours. If you train at IVRO and do the tests in your lab, costs per assay can be as low as $500. IAS test results are available via 1, 2, 3 and 4 sample kits.
