A novel method for the determination of electrical potentials across cellular membranes. II. Membrane potentials of Acholeplasmas, Mycoplasmas, Streptococci and erythrocytes

U Schummer et al. Biochim Biophys Acta. .

Abstract

The membrane potentials of Acholeplasma laidlawii, Mycoplasma mycoides subsp. capri, Mycoplasma gallisepticum, Streptococcus faecalis and human erythrocytes have been determined by applying a novel technique. The membrane potentials were calculated simply from potassium concentrations determined by atomic absorption spectroscopy, and gravimetry. The versatility of the new technique is demonstrated by comparing our results with data obtained by different techniques.
