ABSTRACT
Objective:
To construct and characterize GFP-mfgl 2 fusion protein expression plasmid (pEGFP-mfgl 2) and provide a direct and simplified methodology for primary assessment of the effect of mfgl 2 siRNA on the mfgl 2 gene expression.Methods:
mfgl 2 cDNA was amplified from the mfgl 2 cDNA library pBluescript-m166 (pm166) of mouse genomic P1 plasmid and recloned into pEGFP-N2 upstream of GFP gene. The pEGFP-mfgl 2 was analyzed by restriction endonucleases BamH I and Hind III to ensure the orientation and the sequence. This fusion plasmid was then transfected into CHO cells and the fusion protein expression was observed by fluorescent microscope. Rusults A 1.3 kb long cDNA was obtained. Restriction endonucleases and sequencing assays showed the correct orientation and sequence. After 24-48 hours transfection in CHO cells, the expression of pEGFP-mfgl 2 can be visualized through fluorescent microscope.Conclusion:
pEGFP mfgl 2 has been constructed successfully. The recombinant vector can express GFP-mfgl 2 fusion protein. It provides a direct and simplified methodology for primary assessment of the effect of mfgl 2 siRNA on the mfgl 2 gene expression.
