The express sequence tag(EST) of C-type lectin of Apostichopus japonicus from GenBank was obtained.Based on this sequence,we utilize software of primer 5.0 to design a pair of RACE primer.After the PCR reaction,the cDNA sequence of C-type lectin of Apostichopus japonicus was obtained.Based on part of the known partial cDNA sequence,gene specific primers(GSPF) was designed which work together with universal primers(UPM).The 3' cDNA end of C-type lectin in Apostichopus japonicus was successfully cloned.At the...
RACE(rapid-amplification of cDNA ends)是基于PCR技术基础上,由已知的一段cDNA片段,通过往两端延伸扩增从而获得完整的3’端和5’端的方法[1-2].经典的RACE技术是由Frohman et al.于1988年发明的[3].经过长期的改进,此种方法可以从低丰度的转录本中快速有效的对基因末端进行?
