Chemi-Verse™ PARP7 Assay Kit

The Chemi-Verse™ PARP7 Assay Kit is an ELISA-type chemiluminescent assay designed to measure PARP7 enzymatic activity for screening and profiling applications. PARP7 catalyzes the NAD-dependent ADP-ribosylation of histones. This 96-well or 384-well format assay kit contains sufficient amounts of purified PARP7 enzyme (amino-acids 400- 657), histone mixture, and PARP assay buffer for 100 or 400 enzyme reactions. The Chemi-Verse™ PARP7 Assay Kit takes advantage of a highly specific ADP-ribose binding reagent. First, histone proteins are coated on a 384-well plate. Next, an NAD⁺ substrate is incubated with the PARP7 enzyme in an optimized assay buffer. Finally, the plate is treated with the ADP-ribose specific binding reagent and secondary HRP-conjugated antibody, followed by addition of the ELISA ECL substrate to produce chemiluminescence that can be measured using a chemiluminescence reader.
