  • Title: Effect of ionic charge on detergent-induced hemolysis.
    Author: Pazos-Sanou L, Mata-Segreda JF.
    Journal: Acta Physiol Pharmacol Latinoam; 1989; 39(1):27-31. PubMed ID: 2618747.
    Abstract:
    7.0 microM Sodium dodecyl sulfate induces lysis on A Rh(+) red blood cells 1.6 times faster than the cationic analog dodecyl thiouronium chloride at 37 degrees C and pH = 7.30. Hemolysis isotherms show identical values for the Hill cooperativity parameters of the organic surfactants, but different dissociation parameters. The anionic detergent destabilizes red cell membranes more efficiently than the cationic analog, probably due to the predominance of negative charges on the erythrocyte membranes at physiological pH.
