Binding
ELISA Assay: The HTb-PARP1 positive clones were obtained using the full-length PARP1 plasmid, through PCR amplification, enzyme digestion, ligation, and transformation into DH5a. The plasmids were extracted and determined by enzyme cleavage, and then transformed into DH10Bac. Bacmid/PARP is determined by PCR and sequencing. TNI was transfected, the viruses were collected, and cells were lysed. PARP1 protein was purified by affinity chromatography and determined by Western blotting. A plate was coated by substrate histone, NAD+ and DNA, as well as expressed PARP1 enzyme, was placed into 96-well plate reaction system. Various reaction conditions were optimized and ultimately determined.
