1 The ability to separate the isoforms of human tumour suppressor protein p53 expressed in insect cells using heparin-Sepharose correlates with differences in the isoelectric point of p53, demonstrating that p53 can be heterogeneously modified and providing support for the use of insect cells as a model system for identifying novel signalling pathways that target p53.
