The use of a radioimmunoassay test to measure and to characterize a serine protease involved in growth-related metabolism in a crustacean


, : The use of a radioimmunoassay test to measure and to characterize a serine protease involved in growth-related metabolism in a crustacean. Oceanis 18(1): 93-98

A radioimmunoassay was used to measure and to follow during purification a serine proteinase extracted from the hepatopancreas of a tropical prawn Penaeus vannamei, which had a molecular weight around 25 kD and had collagenase, trypsin and elastase activities. After the sequence determination and a study of the biochemical properties, it was found to be very similar to crab collagenase 1.
