GPCR cAMP Product Solutions

Homogeneous cAMP Detection Assay Solutions for Small Molecules and Biologics

cAMP cell-based assays measure cAMP levels in cells as a direct indication of GPCR functional status (activation or inhibition). This direct measurement is obtained by quantifying cellular cAMP accumulation levels in a dose-dependent manner with cell-based assays that are homogeneous and scalable.

Eurofins DiscoverX® provides robust, easy-to-use, and high throughput screening (HTS) HitHunter® cAMP cell-based assays that accurately detect cellular cAMP levels in a variety of applications without the need for wash steps, optimization, or specialized equipment. These versatile assays provide a simple, validated detection system, optimized with over 125 cAMP Hunter™ cell lines, and include large signal-to-background, gain-of-signal responses. They can be used to monitor GPCR activation or inhibition with cAMP Hunter, ChemiSCREEN™, or non-Eurofins DiscoverX cell lines. Easily obtain reproducible results with high sensitivity, rank order ligands based on molecular potency, or determine pharmacological profiles of your ligands.

Used in the screening of millions of data points and referenced in hundreds of peer reviewed publications ranging from basic research to clinical applications, these assays provide accurate pharmacology of your ligand or small molecule and biologics while giving you the flexibility to work with multiple cell lines.

Product Types

  • HitHunter cAMP Assays – Accurately detect cellular cAMP levels using biologics or small molecules ligands in a variety of applications. These Enzyme Fragment Complementation (EFC) based assays monitor GPCR activation through chemiluminescent detection of cAMP production in cAMP Hunter cell lines as well as non Eurofins DiscoverX cell lines.
  • GPCR cAMP Accumulation Bioassay Kits – Ready-to-use cell-based assay kits with a simple, homogenous protocol and are provided as qualified or target-based. These physiologically relevant, robust bioassays are fit-for-purpose for use in screening and characterization applications to potency testing in quality control lot-release programs. Learn more about Bioassay Kits.
  • GPCR cAMP Accumulation eXpress Assay Kits – Ready-to-use cell-based assay kits for quick analysis and implementation in early discovery phases for screening applications, proof-of-concept, mechanism of action confirmation, and rank-ordering studies. Learn more about eXpress Assay Kits.
  • GPCR cAMP Hunter Cell Lines – Naturally coupled, stable cell lines qualified to use with chemiluminescent EFC-based HitHunter® cAMP Assays, AssayComplete cell culture reagents, and control ligands. Learn more about Stable Cell Lines.
  • ChemiSCREEN Cell Lines and Ready-to-assay Frozen Cells – Cells based on our proprietary Chem-1 and related host cell backgrounds that contain an endogenous expression of Gα15. Gα15 is a promiscuous G protein to help funnel signaling to a common calcium readout, regardless of G protein coupling status. Use cell lines or frozen cells with chemiluminescent or fluorescent assays, and parental cell lines to generate your own GPCR stable cell lines. Additional second messenger signaling, e.g. calcium mobilization, and ERK phosphorylation, for most targets can be used to perform orthogonal assay confirmation.
  • ChemiBRITE Cell Lines and Ready-to-assay Frozen Cells – Cells engineered to flash with added brightness upon GPCR activation and developed to provide the greatest readout flexibility, including luminescent and fluorescent calcium flux as well as cAMP. These cells express a proprietary mutant version of clytin, a calcium activated photoprotein.
