在进行聚合酶链反应(PCR)时,给出了避免DNA污染的提示(由于该过程的敏感性,这是一个严重的问题)。建议实验人员物理隔离PCR制剂和其他实验产品、高压灭菌液、等分试剂,使用一次性手套,避免飞溅,使用正位移移液器,预混试剂,最后添加DNA并仔细选择阳性和阴性对照(包括“无DNA”对照)。设备应用1小杯~ m盐酸洗涤。
Hints are given for avoiding DNA contamination when performing the polymerase chain reaction (PCR) (which is a serious problem because of the sensitivity of the process). Experimenters are advised to physically isolate PCR preparations and products from other experiments, autoclave solutions, aliquot reagents, use disposable gloves, avoid splashes, use positive displacement pipettes, premix reagents, add DNA last and choose positive and negative controls carefully (including a "no DNA" control). Equipment should be washed with 1 smallcap˜m HCL.
