Fig. 5. Temporal complexes between p53, Mdm2 and PML. WS1 cells were treated with
UVC (35 J/m2) and were incubated for the given time. (A) Cellular
lysates were precipitated with an p53 antibody mix (DO1, PAb1801, PAb421) or
precipitated with a PML antibody (PG-M3). The immunoprecipitates were blotted
against p53 (FL-393), Mdm2 (antibody mix of 2A10, IF2, SMP-14) or PML (H-238)
as indicated. (B) Insoluble fractions of p53, Mdm2 and PML. Following
UVC-treatment, the cells were lysed with NP-40 lysis buffer and the
NP-40-insoluble pellet was analysed by immunoblotting as indicated. (C) WS1
cells were extracted in Laemli sample buffer and total levels of p53, Mdm2 and
PML were analysed by western blotting.
