The main conclusions are as follows:The vitellin of Chrysopa septempunctata was extracted with 0.4mol/L NaCl and then precipitated in cold distilled water. Ion exchange chromatography and proteic gel recovery were used to purify it further. SDS-PAGE analysis shows that the vitellin is composed of two subunits, the large one 165kDa and the small one 46kDa.Then automatic amino acid analyzer was used to analyse amino acid composition of vitellin.
