[An XcmⅠ-generated T vector and its applications in synthetic biology]

For more economical and efficient DNA clonging, pFL-XS-T, a Biobrick-T vector was constructed based on pMD18-T vector, carrying clonging regions of XbaⅠ-XcmⅠ-XcmⅠ-SpeⅠ. The results revealed that PCR products could be conveniently inserted into pFL-XS-T vevtor digested by XcmⅠby means of TA cloning. The positive frequency of recombination can meet the experimental requirements and all the plasmids obtained meet Biobrick standard. Moreover, the pFL-XS-T is compatible with other Biobrick parts, and serves as a vector for functional DNA fragments screening.
