Specificity of 53BP1-reactive monoclonal antibodies (MAb). Nuclear extracts of nontransfected cells and whole cell extracts from cells stably expressing HA-tagged full-length or truncated 53BP1 proteins were immunoblotted (IB) with a 53BP1-reactive monoclonal antibody (clone WI1) at a 1:20 dilution or an HA tag–reactive polyclonal antibody (PAb; clone Y11) used at a 1:1,000 dilution. Endog., endogenous.
