{pboot:if('ATM (Phospho Ser1981) Monoclonal Antibody detects endogenous levels of Phospho Atm around the phosphorylation site of S1981(human), S1896(mouse), S1927(rat) protein.The name of modified sites may be influenced by many factors, such as species (the modified site was not originally found in human samples) and the change of protein sequence (the previous protein sequence is incomplete, and the protein sequence may be prolonged with the development of protein sequencing technology). When naming, we will use the "numbers" in historical reference to keep the sites consistent with the reports. The antibody binds to the following modification sequence (lowercase letters are modification sites):EGsQS'!='')} {/pboot:if}
