摘 要: | 根据已获得的辽宁碱蓬甜菜碱醛脱氢酶cDNA的部分序列,设计一条基因特异性引物,与通用引物并用,一步PCR成功地克隆了辽宁碱蓬甜菜碱醛脱氢酶cDNA 3′末端。与常规的3′RACE法相比,一步PCR法具有快速、简便、经济等优点,是一种非常快捷的扩增cDNA 3′末端序列的方法。Abstract:Based on part of a known cDNA sequence of Suaeda liaotungensis betaine aldehyde dehydrogenase,we successfully cloned the 3′cDNA end of S.lianotungensis betaine aldehyde dehydrogenase using one step PCR with a gene specific primer and universal primer.Compared with the typical 3′ RACE,one step PCR is rapid,simple and inexpensive.It is very rapid to amplify an unknown cDNA 3′end using this method.
