外源基因能否在转基因动植物细胞中正确表达,以及如何在翻译水平上定量检测表达产物是基因工程中的关键问题。异戊烯基转移酶(ipt)等基因表达产物在生物体中的微量存在,给转基因研究带来很大困难。本文介绍了一种简便的方法来测定微量的、难以纯化的基因表达产物。该方法包括根据cDNA序列预测并合成抗原肽,将合成的抗原肽与载体蛋白偶联,产生针对合成抗原的特异性抗体,并通过ELISA和Western blot检测基因表达产物。
It is a crucial problem in gene engineering whether an exogenous gene could be correctly expressed in cells of transgenic animal or plant, and how the expression products could be detected quantitatively in translational level. It is very difficult to analyze some gene expression products, such as isopentenyl transferase (ipt), in transgenic investigation because they are trace in organisms. A convenient method is described to determine trace content gene expression product which is hard to purify. The method includes predicting and synthesizing the antigenic peptide according to the cDNA sequence, coupling the synthetic antigenic peptide with carrier protein, raising specific antibodies against the synthetic antigen, and detecting the gene expression product by ELISA and Western blot.
