GPCR Panel Assay
We provide reliable and comprehensive human/mouse GPCR panel assay services on our proprietary functional assay platform (Patent Publication Number WO/2020/026979).
Our panel services include
- FlexPanel48, focused panels with 48 GPCRs.
- large-scale comprehensive panels covering a maximum of 294 human GPCRs and 250 mouse GPCRs.
The receptors eligible for our panel assays are listed at the bottom. If you have any questions, feel free to ask us.
FlexPanel48
FlexPanel48 is a series of focused panels with 48 receptors consisting of custom panels and therapeutic area panels.
Custom Panels
- One can choose 48 receptors from the >550 human/mouse GPCRs on our list.
- Two assay modes, the agonist and antagonist modes, are available. Orphan GPCRs are assayed in the agonist mode only.
- The two assay modes may coexist in a single panel.
- One can replace receptors in a panel with other human receptors or mouse orthologs.
FlexPanel48 Therapeutic Area Panels
13 Therapeutic Areas
- Immunology/Infection
- Oncology

- Assorted are the 48 GPCRs with high disease-gene association scores according to the DisGeNET database.
- The receptors in each panel are listed below.
- Two assay modes, the agonist and antagonist modes, are available.
- The two assay modes may coexist in a single panel.
Panel Assay Examples
FlexPanel48 Endocrinology/Metabolism Panel
TAK-875, a Phase 3 antidiabetic, was screened in the agonist mode in the FlexPanel48 Endocrinology/Metabolism Panel (Figure 1). TAK-875 selectively activated free fatty acid receptor 1 (FFAR1). Next, TAK-875 was shown to activate FFAR1 in a concentration-dependent manner (Figure 2).

FlexPanel48 Psychiatry Panel
Naloxone, the opioid reversal drug, was screened in the antagonist mode in the FlexPanel48 Psychiatry Panel (Figure 3). Naloxone selectively antagonized opiate receptors OPRD1, OPRK1, and OPRM1. Next, naloxone was shown to antagonize the three opiate receptors in a concentration-dependent manner (Figure 4).

Large-Scale Comprehensive Panels
Our large-scale panel assays allow comprehensive screening for up to 294 human GPCRs and >250 mouse orthologs.
The total of >550 human and mouse GPCRs amenable to panel assays are listed below.
Panel Assay Example
Carvedilol, an anti-hypertensive agent, was screened in the antagonist mode for 200 non-orphan GPCRs (Figure 5). Carvedilol selectively antagonized α1A, α1B, α1D, β1, and β2 adrenoceptors. Next, carvedilol was shown to antagonize the above receptors in a concentration-dependent manner (Figure 6).
