Recombinant Adenovirus Infected HaCat Cells Express Human Kerotinocyte Growth Factor (hKGF)

Human kerotinocyte growth factor (hKGF) gene amplified by PCR was inserted into the shuttle vector pAdTrack-CMV to get the recombinant plasmid pAdTrack-CMV-hKGF, which was linearized with Pme I and transferred into Escherichia coli BJ5183 containing the adenoviral bone plasmid pAdEasy-1 to obtain the recombinant adenoviral plasmid pAdEasy-hKGF. The recombinant adenoviral plasmid was then transfected into HEK-293 cell lines via Lipofectamine 2000 to package and amplify the recombinant adenovirus containing hKGF gene detected by PCR. The recombinant adenovirus produced could effectively infect HaCat cells. The result of Western blotting showed that HaCat cells infected with the recombinant adenovirus expressed and secreted hKGF protein.
