PARPtrap™ Combo Assay Kit for PARP1 and PARP2
The PARPtrap™ Combo Assay Kit for PARP1 and PARP2 is a kit designed to measure DNA complex formations of PARP1 and PARP2 enzymes in a high throughput screening assay using fluorescence polarization (FP). The key to the PARPtrap™ Combo Assay Kit are the fluorescent-labeled DNA probes recognized by PARP1 and PARP2. In the absence of ribosylation, PARP1/2 binds to the DNA fluorescent probe, forming a large complex and resulting in the emission of highly polarized light. However, after autoribosylation, PARP1/2 dissociates from the oligonucleotide duplex, which then rotates freely, emitting less polarized light (Fig. 1). Addition of a PARP inhibitor results in trapping of PARP1/2 to the fluorescent-labeled DNA, and increases the FP signal in a dose dependent manner. The combo kit is particularly useful to directly and specifically compare, in a single assay, the effect and potency of a compound on PARP1 and PARP2. The PARPtrap™ Combo Assay Kit for PARP1 and PARP2 is a homogeneous fluorescence polarization assay. The FP signal is measured using a fluorescent microplate reader capable of measuring fluorescence polarization.
