Used in biomedical research to quantify poly ADP-ribose polymerase (PARP) levels in cell or tissue samples. Helps assess DNA damage and repair activity, as PARP is activated in response to DNA strand breaks. Commonly applied in studies related to cancer, neurodegenerative diseases, and apoptosis. Enables researchers to evaluate the effectiveness of PARP inhibitors in therapeutic development. Suitable for high-throughput screening and mechanistic studies in molecular biology and pharmacology.
