Fig. (2) Interactions between rp eL42 and the p53 protein as revealed by co-immunoprecipitation and western blotting.Immunoprecipitation of eL42 followed by incubation with p53, and vice versa, with (a): immunoblotting by means of anti-p53 (DO7) antibodies diluted 1/100.000; (b): detection of the interaction between eL42 and p53 with the anti-eL42 antibodies diluted 1/10.000. M: protein molecular mass standards; SN1: the supernatant after stopping the co-immunoprecipitation reaction; SN2: the first supernatant after the first wash; P: the pellet of immunocomplex containing the antibodies, the protein of interest and the antigen-associated proteins.
