摘要:

基因(组)操作者常会遇到高GC序列难于扩增的问题。全球范围内也还没有很成熟的通用方法来解决这个问题。经过系统的摸索,发现选用有机试剂乙二醇和1,2-丙二醇能得到比较满意的特异的PCR产物。104段随机选取的GC含量在60%~80%之间的人类基因组序列(长度在700~800bp)基本上全部得到较好的扩增。

关键词: 高GC序列;乙二醇;1,2-丙二醇;PCR    
Abstract:

Investigators in gene (genome) manipulation frequently meet difficulty in amplification of GC-rich DNA sequences. This difficulty has not been well solved worldwide. Through systematic screening, 1,2-propanediol and ethylene glycol were found specifically efficient in enhancing the amplification of high GC content human genomic DNA. We randomly selected 104 GC-rich sequences (GC content from 60% to 80% and length from 700 to 800bp) from human genomic DNA to test the two organic solvents and all 104 amplicons were well amplified.

Key words: GC-rich;Ethylene glycol;1,2-propanediol;PCR
