Hela cells were transfected with His-tagged ubiquitin, HA-tagged c-Myc without or with Gfi1 using Mirus Transfection Reagent. After incubation for 30 h, cells were treated with MG132 (40 µM) for 6 h and lysed in SDS lysis buffer. Samples were boiled for 10 min, sonicated briefly and diluted 1:10 with dilution buffer. After centrifugation, samples were subjected to immunoprecipitation using the anti-HA antibody under denaturing conditions prior to Western blot analysis.
