[Characterization of secondary vitellin in the crustacean Brachyura Carcinus maenas]

The secondary vitellin was chromatographically purified and characterized in the crab, Carcinus maenas. It was a lipoglycoprotein of molecular weight 500,000. After dissociation, we observed two major sub units (82,000 and 72,000, respectively), and many lighter minor fractions. These results are compared with those described for some other Crustacea.
