title: Large-scale isolation of proteins of the large subunit from Escherichia coli ribosomes.
abstract: A strategy has been developed and optimized that allows the isolation of proteins of the large subunit from Escherichia coli ribosomes and combines the following advantages: speed, applicability for the isolation of milligram amounts of a single protein, and preservation of the biological activity of the proteins. The method consists of the following steps: ion-exchange chromatography on MonoS and MonoQ, gel filtration on Sephadex 75, and salt washes. Eleven proteins can be purified by a single chromatographic step, and a combination of two steps enables the isolation of the other proteins.
