PARP1, His Tag Protein

The PARP1 activity was assayed with ELISA. The reaction was performed by: 1). Histone protein was coated on a 96-well plate. 2).A biotinylated NAD+ mix is incubated with varying different concentration of the PARP1 enzyme and an activated DNA. 3).The plate was treated with streptavidin-HRP followed by addition of the ELISA ECL substrate to produce chemiluminescence. Finally, measured the signal using a chemiluminescence reader.
