Abstract :

 A pair of corpuscles of Stannius are present embedded in the posterior portion of the kidney in the freshwater fish, Notopterus notopterus. In the present study molecular weight and nature of secretion from these endocrine glands were analysed. The corpuscles of Stannius gland extract was prepared and the homogenate was processed for analysis by applying SDS-PAGE method. The results indicate that the products of corpuscles of Stannius of the fish, Notopterus notoptures is a protein having molecular weight of 41 kDa which is a hypocalcaemic hormone (hypocalcin) as reported in other fishes.
