Genetic re-sources, including pedigree information, blood sample, and tissues, etc., are essential materials for finding of thelinked locus and gene for certain genetic disease. Genome wide scanning, positional cloning and candidate ap-proach are most widely used methods or strategy, by which, thousands of diseases responsible genes have been i-dentified.

文摘遗传多样性及其资源保存的研究,是全球性生物多样性研究的重要组成部分。人类突变细胞的保存,不但是研究人类生物学特征的资源,也是在细胞和分子水平上开展遗传病基础研究的材料。本文应用浓缩的 EBV(Epstein-Barr Virus)液转化外周血 B 淋巴细胞,同时加入环孢霉素(Cyclosporine)抑制 T 淋巴细胞,整个建株过程不需 CO_2孵育箱,建株成功时间在20天左右,且成功率达95—100%,为人类突变细胞的收集、永久保存及其在基因定位、基因克隆等方面的应用创造了条件。
