In the present study we investigated a new approach for studying the interaction between p53 and MDM2/X. The method is based on the different mobility between the interacting domains of the oncosuppressor p53 and its protein ligands MDM2/X on polyacrylamide gels under native conditions. While the two proteins MDM2/X alone were able to enter the gel, the formation of a binary complex between p53 and MDM2/X prevented the gel entry. The novel technique is reliable for determining the different affinity elicited by MDM2 or MDMX towards p53, and can be useful for analyzing the dissociation power exerted by other molecules on the p53•MDM2/X complex.
