| 摘 要： | 在研究转基因香石竹品系月之霓裳（Moonshade）、月之伊人（Moonlite）中外源基因F3’5’H的表达中,本文克隆了F3’5’H全长基因1.5kb,构建获得工程菌株Escherichia coli BL21（DE3）（＋F3＇5＇H）。SDS-PAGE分析的结果显示,该菌株高效表达出F3’5’H重组蛋白,约占菌体总蛋白的30%。用经纯化的F3’5’H重组蛋白作为抗原,制备F3’5’H重组蛋白的抗血清,经ELISA免疫学分析表明,该抗血清的效价为1：25600。Western blot结果表明F3’5’H重组蛋白具有良好的IgG结合活性,且抗血清与转基因香石竹品系月之霓裳和月之伊人中的外源基因F3’5’H所表达的蛋白发生明显的抗原抗体反应。这样,月之霓裳和月之伊人用于评价转基因香石竹品系的环境安全性在我国也得到了验证。

| Abstract: | In order to study the expression of exogenous gene F3'5'H in transgenic carnation lines Moonshade and Moonlite,the full-length F3'5'H gene of 1.5 kb was cloned,and the strain Escherichia coli BL21(DE3) (+F3'5'H) was obtained.SDS-PAGE analysis showed that the high-level expressed recombinant protein F3'5'H was detected and the expression level was almost 30% of the total protein.The recombinant protein was used as antigen to obtain the antiserum.And the immunological analysis of ELISA showed the antiserum ti... |
