摘要
针对人骨形成蛋白 3基因的 c DNA序列设计引物 ,通过反转录 PCR技术 ,从人骨纤维肉瘤组织中扩增出目的片段。从胶中回收目的片段 ,将其与 p MD18- T载体连接 ,转化大肠杆菌 DH 5α后 ,经 H ind 酶切鉴定 ,进行测序。结果显示所得到的片段大小为 84 5 bp,与所设计的序列同源性为 10 0 % ,说明已经成功地扩增、克隆了人骨形成蛋白 3(h BMP- 3)基因 c DNA的大部分序列。
A pair of primers for the amplification of partial cDNA sequence of human bone morphogenetic protein 3 gene were designed,the target fragment was amplified by RT PCR from the tissue of human bone fiber sarcoma,then was purified from agarose gels and integrated into pMD18 T vector.After being transformed into E.coli. DH5α,tested by Hin dⅢ restriction endonuclease digestion,the positive clone was sequenced.The sequencing result indicated that the size of the fragment cloned is 845 bp,and its sequence homology with the designed one is 100%.The conclusion can be made that the major part of the cDNA of human bone morphogenetic protein 3 (hBMP 3) gene has been successfully amplified and cloned.
