  • After electrophorised on 1 % agarose gel , the pcr production was purified with agarose gel dna extraction kit . the segment was ligated with vector pmd18 - t and then was tranformed into the competent cell of dh5 a . a construction mstnd - pmd18t was generated by inserting the sequence of 254bp into pmd18 - t vector and selecting the sense clones . positive clone was identified by three ways : endonuclease digestion , pcr and sequencing . the result showed that the cloned sequence coincides with the designed sequence . this construction was digested with nco i and xho i and ligated the pet28a ( + ) vector digested with the same enzymes using dna ligation kit . the production of ligation reaction was transformed into the competent cell of bl21 ( de3 ) . after 12 - 16 hours of culture , several colnes appeared on the plate . some positive clones were selected to extract their plasmid . these plasmids were digested by nco i and xho i and indentified by pcr . a contraction , mstnd - pet28a was generated . the result showed that the cloned sequence coincides with the designed sequence
