Human Phospho-ATM (S1981) PharmaGenie ELISA Kit (SBRS1753)

The Phospho-ATM (S1981) ELISA from Assay Genie enables quantitative measurement of ATM kinase phosphorylated at the serine 1981 autophosphorylation site, a hallmark of DNA double-strand break signalling. The microplate-based immunoassay uses 100 µL of clarified cell or tissue lysate per well, with results read on a standard plate reader after incubation with a phospho-specific detection antibody and TMB substrate. Researchers studying genotoxic stress, radiation response, and ATM-dependent checkpoint control use this kit to compare activated ATM levels across treated versus untreated samples, supporting applications in oncology, radiobiology, and DNA repair pathway research.
