Binding
Biochemical Activity : PARP-1: The autoparsylation assay is performed as 384-well HTRF® (Cisbio, Codolet, France) assay format in Greiner low volume nb 384-well microtiter plates. 35 nM His-tagged Parp-1 (human, recombinant, Enzo Life Sciences GmbH, Lörrach, Germany) and a mixture of 125 nM bio-NAD (Biolog, Life science Inst., Bremen, Germany) and 800 nM NAD as co-substrate are incubated in a total volume of 6 μl (100 mM Tris/HCl, 4 mM Mg-chloride, 0.01% IGEPAL® CA630, 1 mM DTT, 0.5% DMSO, pH 8, 13 ng/μl activated DNA (BPS Bioscience, San Diego, US)) in the absence or presence of the test compound (10 dilution concentrations) for 150 min at 23° C. The reaction is stopped by the addition of 4 μl of the Stop/detection solution (70 nM SA-Xlent® (Cisbio, Codolet, France), 2.5 nM Anti-His-K® (Eu-labelled anti-His, Cisbio, Codolet, France) in 50 mM HEPES, 400 mM KF, 0.1% BSA, 20 mM EDTA, pH 7.0). After 1 h incubation at room temperature the HTRF iss measured with an Envision multimode reader (Perkin Elmer LAS Germany GmbH) at excitation wavelength 340 nm (laser mode) and emission wavelengths 615 nm and 665 nm. The ratio of the emission signals is determined. The full value used is the inhibitor-free reaction. The pharmacological zero value used is Olaparib (LClabs, Woburn, US) in a final concentration of 1 μM.
