摘要:

旨在构建PLCζ真核表达载体,初步研究其在体细胞系中的表达特性。本研究用PCR技术扩增出PLCζ基因片段,克隆至载体pEGFP-N1,鉴定无误后,将构建了重组质粒pEGFP-N1-PLCζ转染293T细胞和绵羊成纤维细胞,在倒置荧光显微镜和激光扫描共聚焦显微镜下观察重组质粒在细胞中的表达和分布。经酶切与测序证明,本试验成功的构建了pEGFP-N1-PLCζ真核表达载体,并且成功与绿色荧光蛋白融合表达。本试验实现了pEGFP-N1-PLCζ在绵羊胎儿成纤维细胞中的表达,这将有利于进一步通过核移植来研究其重组蛋白对卵母细胞的激活作用。

Abstract:

This experiment aimed to construct the eukaryotic expression vector of PLCζ,a preliminary study of its expression properties in progenitor cell line was conducted.PLCζ was amplified by PCR and cloned into vector pEGFP-N1,after correct identification,the recombinant plasmid pEGFP-N1-PLCζ was transfected to 293T cells and sheep fibroblasts.The expression and distribution of cell recombinant plasmid was observed under an inverted fluorescence microscope and laser scanning confocal microscope.After digestion and sequencing,the pEGFP-N1-PLCζ eukaryotic expression vector was successfully constructed,and its successful fusion expression with the green fluorescent protein was observed.This experiment realized the expression of pEGFP-N1-PLCζ in sheep fetal fibroblast cells,which will help us to study the activation of recombinant protein on the oocyte through nuclear transfer furtherly.
