NR Selectivity Screening

We can test your drug candidates for selectivity amongst Nuclear Receptors

We can test your compounds with metabolic effect but unknown target whether they influence activity of any Nuclear Receptor.

We can screen your chemicals for potential endocrine disrupting activity at all relevant Steroid and other Nuclear Receptors.

Phenex has established 27 nuclear receptor cellular reporter assays, the largest battery of nuclear receptor assays you find worldwide. Phenex offers these high quality assays in pre-defined panels for selectivity screening (see: panels). The assays can be run in agonist and antagonist mode. As a result of a service project we deliver 11 point dose response curves including EC50/IC50 determination and efficacy calculation for all customer compounds in comparison to a reference compound as well as an overview matrix, showing efficacy and potency of all compounds tested.

Customers can choose between the following panels:

- Full Phenex panel (27 NRs, cellular assays)
- Selectivity Overview panel (17 NRs, cellular assays)
- Xenobiotic panel (PXR/SXR, CAR, FXR in different species)
- Metabolic Effect FRET panel (PPARα,β/δ,γ, LXRα,β, FXR, VDR, TRα,β, ERβ, ERRα,γ, RXRα)
- Endocrine Disruptor Panel (ERα,β, ERRα,β,γ, AR, TRα)
