Abstract:
Objective:To observe the transfection efficacy and targeting efficiency of hepatitis B virus envelope(HBVE) as a gene transfer vector for liver cancer cells.Methods:HBVE was obtained from the supernatant of HepG2.2.15 cells with a PEG8000 system and ?-propiolactone.The pIRS2-EGFP was packed with HBVE to obtain HBVE-GFP and was packed with liposome to obtain Liposome-GFP.HBVE-GFP and Liposome-GFP were used to transfect human hepatoblastoma cell line HepG 2 to study the transfection efficiency.HepG 2,A 549,HeLa and FB cells were transfected with HBVE-GFP to appraise the targeting ability of HBVE-GFP.GFP protein expression was observed under a fluorescent microscope and the ratio of GFP positive cells was determined by flow cytometry.Results:(1) Transfection efficiency:The GFP protein was observed in both the liposome group and the HBVE group under the fluorescent microscope;the fluorescent intensity in the HBVE group was 3-4 times that of liposome group as determined by flow cytometry(P
