Human Phospho-ATM (S1981) and Total ATM PharmaGenie ELISA Kit (SBRS1754)

ATM is a key regulator of the cellular DNA damage response, and phosphorylation at Ser1981 marks its activated state following double-strand breaks. This dual-target ELISA from Assay Genie enables simultaneous quantification of phospho-ATM (S1981) and total ATM protein from a single lysate, supporting studies of genomic stability, checkpoint signaling, and radiosensitivity in human cell and tissue lysates. Each microplate includes all reagents needed for 96 determinations, with roughly 100 µL of prepared lysate required per reaction. Store the kit refrigerated and protected from light to maintain antibody binding activity and substrate stability. Intended for research use only.
