The content variation to Chrysopa septempunctata"s vitellin was detected through ELISA. It indicated that vitellin was utilized gradually during embryonic development, and a fallowing trend in form of straightline was found in the whole embryonic development. Vitellin couldn"t be detected in just hatched larvae.

通过ELISA来测定大草蛉的胚胎发育和胚后发育中卵黄蛋白的含量变化，随着胚胎的发育，卵黄蛋白逐渐被利用，在整个胚胎发育过程中呈直线下降趋势，在刚孵化的幼虫中已检测不到卵黄蛋白的存在。

Vitellin was isolated and purified from the eggs of a water wolf spider, P. piraticus.

从真水狼蛛Pirata piraticus卵中提取出了雌性特异性蛋白质——卵黄蛋白。

According to amino acid sequence to vitellin which has the structural character of GL/ICG motif near C end, two degenerate primers were designed and Chrysopa septempunctata s RNA was extracted, and a 900bp fragment was amplified by RT-PCR.

根据昆虫卵黄蛋白氨基酸序列在靠近C端存在GL／ICG区域的结构特点，设计了两条简并引物，提取大草蛉的RNA，用Takara的3′—RACE试剂盒进行RT-PCR，扩增出一段900bp的片断。

The variation to vitellin polypeptide was studied by SDS-PAGE during embryogenic and postembryonic development to Chrysopa septempunctata. The results indicated that vitellin was degradated constantly during embryonic development, and the bands of vitellin couldn't be detected in the 4th day of ovum development.

用SDS-PAGE研究了大草蛉胚胎发育和胚后发育过程中卵黄蛋白多肽的变化动态，结果表明，卵黄蛋白在胚胎发育过程中被不断降解，在卵发育的第4天已经基本上看不到卵黄蛋白的条带。

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.

主要结论如下：用蒸馏水沉淀法对大草蛉的卵黄蛋白进行了初步纯化，而后又采用离子交换层析和蛋白胶回收的方法对卵黄蛋白进行了进一步的纯化；通过SDS-PAGE分析表明，大草蛉的卵黄蛋白由大165kDa和小46kDa两个亚基组成；用氨基酸自动分析仪对纯化后的卵黄蛋白进行了氨基酸组分分析。
