摘要: Four new features have been included in a phage-lambda-replicon-based cosmid vector, Lorist6. A ScaI restriction site allows insertion of blunt-ended DNA, partially digested with AluI or any other enzyme which creates blunt ends after cleavage. NotI and BamHI sites enable construction libraries using double digestion + Sau3AI. The promoter the neo gene has substituted by derived from tet pBR322, increasing expression resistance product. transcriptional terminator placed downstream to prevent transcription into insert DNAs.
