gpcrELECT℠ Personalized Screening & Profiling

gpcrELECT provides you access to the world's largest menu of naturally coupled known, orphan and ortholog GPCR cell lines. Select your target in any one of our convenient assay formats – Arrestin recruitment, 2nd messenger signaling (cAMP or Calcium) or receptor internalization. Screen your compounds against a single GPCR target or design a customized panel of receptors to study off-target selectivity or screen or profile the same target in multiple modes for biased ligand discovery. This simple, fast and cost-effective alternative to in-house profiling and screening is ideal for any size compound collection. gpcrELECT is an extremely flexible solution with multiple applications including, primary HTS & lead discovery and ongoing lead optimization & SAR.

Multiple Assay Readout Options

gpcrELECT lets you screen or profile compounds against your favorite receptor using one of our functional, cell-based assay readouts. Or examine these pathways in parallel for discovery of novel biased ligands with unique attributes.
 

Arrestin

cAMP

Calcium

Internalization

Flexible Options for Mode of Action Studies

With gpcrELECT, you have the ultimate flexibility to screen or profile your compounds in multiple modes making it the ideal platform to provide high quality, functional data to drive all your discovery programs.
 

Agonist & Partial Agonists

Antagonist

Allosteric Modulator

Inverse Agonist

 

Data Analysis & Interpretation 

Definitions

Percent Activity/Inhibition

The results for single concentration (primary screen) for tested compound(s) are reported in your study report and spreadsheets as '% Activity' or '% Inhibition' and are calculated in the following manner:
 

% Activity
(Agonist Mode) =
100% x
 [
Mean RLU (test sample)- Mean RLU(vehicle control)
Mean MAX RLU (control ligand)- Mean RLU (vehicle control)
 ]
 

test sample = client supplied compound
vehicle control = DMSO (0% activity)
control ligand = control compound (100% activity)
 

% Inhibition
(Antagonist mode) =
100% x
 [ 1- 
Mean RLU (test sample)- Mean RLU(vehicle control)
Mean MAX RLU (control ligand)- Mean RLU (vehicle control)
 ]
 

test sample = client supplied compound
vehicle control = DMSO (0% activity)
EC80 control = control compound (80% activity) 
 

Dose Response Curve (EC50/IC50)

The results for 10-point dose response curve compound/target interactions are reported in the study report and spreadsheets as EC50/IC50, which are values derived using the Hill equation:
