RESUMEN
Objective To construct and identify the screening vector pUC18-EGFP,using EGFP as an indicator. Methods The EGFP gene was prepared by PCR and cloned into pUC18 resulting the vector pUC18-EGFP. Then DNA fragment was inserted into the MCS of pUC18-EGFP to test its practicability based on green fluorescence. Results The pUC18-EGFP was confirmed correctly by restriction enzyme analyses. The pUC18-EGFP was used to select recombinants. The green strains on the plate were confirmed by restriction enzyme and DNA analyses,which were E.coli harboring recombinants. Conclusion The screening vector PUCl8-EGFP was constructed successfully. Thus,we can select the positive clones on plates based on the green fluorescence of EGFP.
