Abstract 2-phenoxyethanol was tested as a preservative for plankton samples intended for electrophoretic analysis of enzymes. Esterase, a-glycerophosphate dehydrogenase, glucosephosphate isomerase, isocitrate dehydrogenase, lactate dehydrogenase, malate dehydrogenase, phospho-glucomutase, and superoxide dismutase were tested in starch gels. Adult skeletal muscle tissues retained enzyme activity for five of the enzymes tested. No activity was detected in eight larval species analysed for the same eight enzymes. 2-phenoxyethanol is unsuitable as a biochemical preservative for plankton samples but may find an application for adult muscle tissues.
