Objective:To construct the eukaryotic pEGFP-hElf5 and identify the subcellular localization of Elf5 in MCF7 cells. Methods:Elf5 fragment was subcloned into pEGFP-C1 after PCR. The plasmid was verified by en-zyme digestion,DNA sequencing and its expression was subsequently checked by Western blot. Immunofluorescence was used to identify its subcellular location. Results:Elf5 was subcloned into pEGFP-C1 successfully. Conclusion:Eukaryotic pEGFP-hElf5 was constructed successfully and Elf5 locates in cell nucleus.
