Rapid separation of Escherichia coli 30S ribosomal proteins by fast protein liquid chromatography (FPLC).
The proteins of the 30S ribosomal subunit from Escherichia coli have been separated by reverse-phase high-performance liquid chromatography on a short alkyl chain (C1/C8)-coated phase. The reverse-phase column was connected to a fast protein liquid chromatography (FPLC) system. The 21 proteins of the 30S ribosomal subunit were resolved into 16 peaks. Eleven proteins were isolated in purified form in a single chromatographic run as shown by polyacrylamide gel electrophoresis and amino acid analysis. Interestingly, the retention times of some proteins differed from the retention times observed on other reversed-phase support materials. The results show the speed and resolution of reverse-phase FPLC for both analytical and semi-preparative separations of 30S ribosomal proteins.
