Assay-Ready GPCR Kits
Ready-to-use complete kits for:
• Profiling of lead compounds
• Selectivity and specificity panels
• Antibody screening
• Biomarker detection in blood and plasma
• Compound dosing prior to animal studies
Now you can access our extensive menu of over 400 functional, whole cell GPCR
assays without having to invest in a clonal cell line. Our PathHunter® and
cAMP Hunter™ eXpress GPCR assays are ready-to-use complete kits that contain all the
necessary reagents to perform a functional whole cell assay including frozen pre-validated
cells, detection reagents, media and plates and do not require expensive instrumentation to
run. Eliminate lengthy, expensive and time consuming cell culture. Simply thaw, plate and
run the assay!
cAMP Hunter™ eXpress GPCR Assays provide a fast
and simple assay for detection of second messenger signaling for even the most difficult GPCR targets.

PathHunter® eXpress β-Arrestin GPCR Assays provide
a direct measure of GPCR activation by monitoring β-Arrestin binding to the GPCR of interest
and can be used with any Gi-, Gq-, Gs-coupled receptor. Assays are available for known and
orphan GPCRs and non-human ortholog receptors Learn more»
New! PathHunter® eXpress GPCR Internalization Assays are
a non-imaging, non-antibody based platform that provides a quantitative measure of internalized
GPCR localized to the early endosome. Learn more»
