3.1. The construction of pBC-hygro-GFP
3.1.1. Amplifiedgfpfragment
pEGFP was used as the template to augment PCR, whose products went through agarose gel electrophoresis to produce a 900 bp strip. As the fragment corresponded with what was required, itwas indicated that the primer design and PCR reaction procedure conformed to the requirements of augmentation. Through enzyme digestion of PCR products with HindIII and ECOlI, cohesive terminus matched with the fragment was acquired (enzyme digestion products map of electrophoresis).
3.1.2. Extraction and enzyme digestion of PBC-hygro plasmid
PBC-hygro plasmid with hygromycin resistant gene was ex-tracted, and after detected by agarose gel electrophoresis, a plasmid fragment of about 6.8 kb was obtained, the size of which corresponding to that showed in the plasmid profile. Through the enzyme digestion of plasmid PBC-hygro with HindIII and ECOlI, two fragment with 2 kb and 4.8 kb were obtained, and the 4.8 kb fragment purified.
