title: Ribonucleic acid regulation in premeabilized cells of Escherichia coli capable of ribonucleic acid and protein synthesis.
abstract: A cell permeabilization procedure is described that reduces viability less than 10% and does not significantly reduce the rates of ribonucleic acid and protein synthesis when appropriately supplemented. Permeabilization abolishes the normal stringent coupling of protein and ribonucleic acid synthesis.
