Abstract

The suitability of polystyrene-divinylbenzene reversed-phase HPLC columns for rapid separation and purification of acid-soluble nuclear proteins was evaluated. We used a polystyrene-divinylbenzene reversed-phase HPLC column (PLRP-S) for purification of nuclear proteins extracted with 0.3 M HCl or 5% HClO4. We are able to obtain electrophoretically pure fractions for a number of nuclear proteins including HMGI4, HMG17 and variants of histone H3. The identity of proteins in these fractions was confirmed by immunochemical analysis, protein sequencing, mass spectrometry and migration on two-dimensional polyacrylamide gel electrophoresis. These methods do not require special preparation of the sample and are quicker than similar published methods.
