Abstract
The effect of photodynamic action on plasma membranes was examined using a fluorescent potentiometric indicator [di-SBA-C2(3)] to measure alterations in the plasma membrane potential of mouse myeloma cells treated with zinc phthalocyanine sulfonate and light. Plasma membrane depolarization was observed to be an early event in photodynamic action, showing both photosensitizer concentration and light dose dependence. Depolarization occurred while membrane integrity was retained and appears to be an early event preceding cell death.This publication has 21 references indexed in Scilit:
