Target Engagement Assays

Universal Cell-based Compound-target Binding Assays

Target engagement assays measure compound binding to a specific protein target. In a cellular environment, these assays monitor compound cellular penetration and compound-target interaction to enable the assessment of compound efficacy and confirmation of mode-of-action.

InCELL cell-based compound-target engagement assays provide the ability to confirm compound cell entry and protein target binding, screen and rank inhibitors, validate hits identified in biochemical assays, and measure cellular EC50 values all in the native cellular environment. These simple binding assays require no custom chemical tracers nor antibody reagents and provide a convenient solution when functional assays are difficult or unavailable.

Access two leading Eurofins DiscoverX® assay platforms, InCELL Pulse and InCELL Hunter — both based on the industry validated EFC technology with similar underlying principles, but crucial differences that suit them for different protein targets. The InCELL Pulse platform is built on the principle of protein thermal stability, while InCELL Hunter is built on the principle of protein stabilization related to protein turnover or interaction disruption.

InCELL target engagement assays are a perfect complement to Targeted Protein Degradation (TPD) programs that allow you interrogate and optimize target-binding portion. Discover the power of the InCELL assays and take advantage of stable cell lines, ready-to-use kits, and a do-it-yourself, starter kit perfect for creating your own compound-target engagement assay.
