ELECTROPHORETIC PROTEIN PROFILES OF DIFFERENT TISSUES OF LAMELLIDENS MARGINALIS (LAMARCK) FROM KAGDIPURA SWAMP

EIectrophoretc protein pattern of different tissues viz, gonad, hepatopancreas, foot, mantle, gill, anterior adductor muscle, posterior adductor muscle and siphon of Lamellidens marginalis from Kagdipura swamp was studied during summer season (2001). Study revealed that, protein bands were found to be maximum (5) in the foot while minimum (2) in the mantle. Among the different tissues, total 6 different protein bands were observed, ranged from 0.0408 REM and 86,377 Da to 0.9592 REM and 10,943 Da. It was pointed out that protein band Ill with REM 0.3673 and MW 41,440 Da was occurred only in gills. It was found that fast moving fractions were occurred in all the tissues, slow moving protein fractions were absent in the gills whereas intermediate fractions were absent in case of the anteriorand posterior adductor muscles, mantle and gonad. It was pointed out that the proteins of specific molecular weight are present in specific physiological important tissues and decrêase in the number of protein fractions and simplifkation of molecular structure might be due to functional requirements of the tissue.
