Abstract

Two yolk proteins (YP1 and YP2) from the ovaries of Indian major carp, Labeo rohita were isolated by gel filtration and partially characterized by the use of hydroxyapatite ultrogel column in conjunction with native PAGE. On native PAGE YP1 gave a single protein band, whereas YP2 of gel filtration revealed the contamination of YP1, which was removed by adsorption chromatography on hydroxyapatite ultrogel and then the YP2 was the purified one as judged by electrophoresis. Both YP1 and YP2 also stained for lipid and contained alkali-labile phosphorus. Therefore, both yolk proteins were lipophosphoprotein. The molecular weights of YP1 and YP2 were 620 kDa and 225 kDa respectively as determinedby gel filtration on Sepharose 4B. When YP1 and YP2 were compared in relation to some physicochemical characteristics with yolk proteins ofother oviparous vertebrates including fish, they were lipovitellin like. Antiserum to YP2 crossreacted with YP2 and vitellogenin suggestingthat YP2 was the cleaved product of vitellogenin. Anti-YP2 antiserum was not crossreacted with native YP1, whereas reduced and/or denaturedYP1 was crossreacted indicating the presence of antigenic determinants in the inner core region of YP1 polypeptide.
