摘  要:
本试验应用RT-PCR技术,参照Genbank报道的序列,从荷斯坦牛中性粒细胞mRNA中扩增出杀菌/通透性增加蛋白(BPI)氮端基因(713bp),并与pGEM-T-easy载体连接,构建基因重组体pGEM-T-easy-BPI,进行序列测定。结果表明获得长度为713bp的BPI氮端基因。序列分析证实该片段与安哥斯牛BPI氮端基因相比有1个点突变,为同义突变。该基因的克隆为进一步表达该基因奠定了基础。

摘  要:
The study aimed to clone cDNA of N-terminal bovine bactericidal/permeability-increasing protein(BPI)and to construct the recombinant plasmid pGEM-T-easy-BPI.According to the sequence in Genbank,the gene which encodes N-terminal BPI protein was amplified by RT-PCR from mRNA that were extracted from the bovine polymorphonuclear neutrophils(PMN).The PCR product was cloned into the pGEM-T-easy vector and the sequence was confirmed by sequencing.The result showed that a 713bp gene was acquired.Compared with the sequence in Genbank,there is a silent mutation of one base pair.
