Signaling Pathways

Elucidate Target-Specific Pathways With a Suite of Cellular Assays

DiscoverX offers a comprehensive collection of cell-based pathway indicator assays designed to detect activation or inhibition of complex signal transduction pathways in response to compound treatment. Based on the proven PathHunter® technology, These biosensor cell lines allow you to measure distinct events within a variety of pathways involved in compound toxicity, cholesterol metabolism, antioxidant function, DNA damage and ER stress. In combination with our biosensor cell lines with fast and simple chemiluminescent detection, DiscoverX Pathway Signaling assays will help you generate cellular pathway selectivity profiles of your compounds without relying on reporter gene assays or complex phenotypic screens.
