A: Transfection efficiency of pEGFP-E7 using MPG in HEK, B: COS-7 and C: TC-1 (C) cells after 48 h: The
expression of E7-GFP using GFP reporter was monitored by Epi-fluorescent microscopy and flow cytometry. E7-GFP
expression in HEK, COS-7 and TC-1 cells was 13.22%, 66% and 2.04% at ratio of 10: 1 and 17.3 %, 67.6 % and 4.61 % at
ratio of 15: 1 as compared to negative control
