Electrophoretic separation of esterases of Alaria marcianae (La Rue, 1917) (Trematoda)

Abstract

1. 1. Disc electrophoresis was used to determine the esterase isoenzymes present in adults of the strigeoid trematode Alaria marcianae (La Rue, 1917). 2. 2. Eight esterase bands were found with α-naphthyl acetate as the substrate and Fast Blue RR as the dye. 3. 3.|From results obtained with inhibitors, four different types of esterases were tentatively identified; cholinesterase (one band), ali-esterase or B-type (one band), arylesterase or A-type (2 bands) and acetylesterase or C-type (4 bands).
