Detection Reagents

DiscoverX offers detection reagents with both chemiluminescent and fluorescent readouts to suit the diverse needs of your drug discovery programs. DiscoverX’s chemiluminescent detection is based on the proprietary Enzyme Fragment Complementation (EFC) technology, while the fluorescent detection is based on an activated fluorescent dyes. These detection reagents are optimized for a variety of applications such as detecting cell-based protein-protein interactions, compound-protein binding, translocation, and second messenger assays.

DiscoverX’s detection reagents are designed for DiscoverX cell lines including cAMP Hunter™, InCELL Hunter™ or PathHunter® cell lines, InCELL assays, and ProLabel®/ProLink™ (PL/PK) expression or cloning vectors inside whole cells.

Product Highlights

  • Sensitive detection and reproducible results providing robust assays you can rely on

  • Easy, one-step addition protocols ideal for multiple basic research and drug discovery applications

  • Scalable from 96- to 346-well formats compatible with high-throughput screening or miniaturization
