| | Chemiluminescent PARP Assay |
| Description: | Tankyrase activity was assayed using a 96-well format HT Universal Chemiluminescent PARP Assay Kit (Trevigen, Inc, cat. no. 4676-096-K) according to the manufacturer's instructions. In short, tankyrase/PARP activity is quantified by the incorporation of biotinylated nicotinamide adenine dinucleotide (biotin-NAD+) onto the immobilised pseudo substrate, Histone. The extent of poly(Biotin-ADP)ribosylation (PARylation) in the presence of increasing dose of inhibitor is then quantified by binding of streptavidin conjugated horse radish peroxidase (strep-HRP) followed by chemiluminescent detection. Prior to assay initiation, inhibitor stocks were prepared in aqueous DMSO (10% (v/v)) from 5 millimolar (mM) stock in 100% DMSO (Sigma Aldrich, cat. no. 265855) as 10x concentrations. For the primary assay (i.e., single dose at 1 micromolar (uM) final concentration) this corresponded to 10 uM in 10% DMSO. |
