Description

The TNKS2 Colorimetric Assay Kit is designed to measure the activity of Tankyrase 2 (TNKS2, also known as PARP5B) for screening and profiling applications. TNKS2 is known to catalyze the NAD-dependent ADP-ribosylation of histones. The key to the TNKS2 Colorimetric Assay Kit is the biotinylated NAD+. First, histone proteins are coated on a 96-well plate. Next, a biotinylated NAD+ mix (termed PARP Substrate Mixture) is incubated with the TNKS2 enzyme. Finally, the plate is treated with streptavidin-HRP followed by addition of the colorimetric HRP substrate to produce color that can be measured using a UV/Vis spectrophotometer microplate reader.

Supplied As

The TNKS2 assay kit comes with purified TNKS2 enzyme, histone mixture, and PARP assay buffer for 100 enzyme reactions.

Materials Required But Not Supplied

DTT (10 mM in water, prepared fresh)
1x PBS (phosphate buffer saline)
PBST: 1x PBS, containing 0.05% Tween-20
UV/Vis spectrophotometer microplate reader capable of reading absorbance at 450 nm*
