| Abstract: | A likely genetic variation in the acid phosphatases from lamprey  kidneys is described. Separations with starch gel electrophoresis have given eight different types, three with one zone of acid phosphatase activity and five with three zones. The molecular weights of these different isoenzymes were determined by gel filtration to be between 81,300 and 87,200. This is compared with existing data in the literature for other acid phosphatases. The most likely interpretation for the described variation is a one-locus, homodimeric enzyme system with four different alleles present in the population investigated. |
