Characterization of antibodies raised against ATM. (A) Three antibodies raised against ATM recognize a 350-kDa band in Western blots of HeLa whole-cell lysates (20 μg) that were separated on 4–12% gradient SDS-PAGE gels. (B) Each of the three ATM antibodies immunoprecipitated a 350-kDa band that is recognized by the other two antibodies on Western blots.
