Tissue esterases of Lamellidens corrianus (Fresh water mussel).

Polyacrylamide gel electrophoretic (PAGE) technique was used to examine the esterase pattern of Ctenidia, Hepatopancreas, Hemolymph, Intestine, Mantle. Foot of the Lamellidens corrianus. The zymograms revealed the varied pattern of esterase both in number and type. This varied pattern suggested several roles for these enzymes present in different tissues.
