Your Source for a Complete Offering of GPCR Solutions

G-protein coupled receptors (GPCRs) play a crucial role in many physiological functions and in the pathology of multiple diseases including cancer, endocrine, and metabolic disorders. These receptors represent the largest class of therapeutic targets. Over 30% of currently marketed drugs target these receptors, while GPCRs continue to be the focus of many active drug discovery programs.

Universal Platform for Ligand Bias and Receptor Deorphanization

PathHunter® β-Arrestin Assays

Monitor activation or desensitization of GPCRs, and regulation of other signaling molecules such as protein kinases by measuring β-arrestin recruitment and binding to the activated receptor. PathHunter β-Arrestin assays offer a powerful and universal functional screening platform that can be applied to virtually any GPCR without imaging, fluorescent protein tags, or radioactivity and offer the ability to multiplex with Ca2+ or cAMP readouts in the same cell line.

Quantitative Primary and Orthogonal Screening Assays for Identifying Safer Drugs

PathHunter GPCR Internalization Assays

Measure GPCR trafficking in live cells with the non-imaging, non-antibody-based chemiluminescent functional assays. PathHunter GPCR Internalization assays are whole cell functional assays that provide a direct and quantitative measurement of internalized GPCRs localized to intracellular endosomes and allow the fate of activated GPCRs to be monitored in live cells without the requirement of antibodies, bulky labels or expensive microscopy equipment.

Simple Assays to Identify and Optimize Pharmacochaperones

PathHunter Pharmacochaperone Trafficking Assays

Identify and characterize compounds which function as pharmacochaperones by promoting proper folding of misfolded protein and assist in trafficking to their intended location. Eurofins DiscoverX’s PathHunter cell-based pharmacotrafficking assays offer a validated, cell-based platform for broad pharmacological characterization and interrogation of compound function in disease processes associated with protein trafficking and internalization due to protein misfolding.

Complete Assay Solutions for Monitoring cAMP

Cell Lines, Frozen Cells, and Kits

Monitor functional status of GPCRs directly by quantifying cellular cAMP levels in a dose-dependent manner. Detect cAMP levels in cell lines, primary cells, membrane preparations, and serum samples with robust, easy-to-use HitHunter® assays. Cell-based assays available in multiple formats for chemiluminescent or fluorescent read-outs.


 

  

Directly Measure Calcium Flux

Cell Lines, Frozen Cells, and Kits

Measure intracellular calcium mobilization in cells based on the activation status of GPCRs and ion channels. Detect calcium flux rapidly with HTS-friendly HitHunter Calcium No WashPLUS kits that are homogeneous assays that provide a fast, reliable, and low cost approach compared to traditional wash and quench-based assays.

High Quality Membrane Preps for Radioligand Binding and Functional GTPγS Assays

ChemiScreen Membrane Preps

Receptor and G-protein binding assays are long-established and successful approaches to identify ligands for GPCRs. Yet, often the most challenging aspect of a radioligand binding or functional GTPγS assay is the generation of reliable, high quality membrane preps. That's why we developed one of the largest collections of commercially available GPCR membrane preps, so you can focus on reviewing results instead of troubleshooting your assays.
