IIVS offers fit-for-purpose assays designed to address individual testing needs. In addition to customized approaches to assessing respiratory insult and injury to the airway tract, IIVS also offers cost-effective screening services to rapidly evaluate compounds and formulations as well. These “off-the-shelf” protocols examine cytotoxicity markers, such as LDH leakage and WST-8 reduction. Additional endpoints such as inflammation and oxidative stress can be assessed as well. IIVS offers this service in 2D models and higher content, endpoint multiplexing in 3D models. Results from the respective test systems can be used to determine whether additional, more comprehensive evaluation of the test material is needed.
