Transfection and expressiOn of green fluorescent protein gene in prostate carcinoma PC-3M cell line / 吉林大学学报(医学版)

Objective：To reseach the expression of green fluorescent protein(GFP)gene in prostate car-cinoma PC-3M cell line and the efffect of cell cycle．Methods：GFP gene recombination DNA was construct-ed and PC-3M cells were transfected with lipofectin regant．The expression of GFP was observed under in-vert fluorescence microscope．Meanwhile，the cell cycle of positive cell colon was assayed by flOw cytome-ter．Resuits：After transfection，about 10％～15％cells expressed green fluorescent protein and there wasno significant change compared the cell cycle of positive cell colon with parents cells．Conclusion：GFP sup-plys a new way in reseaching metabolic phenomenon of live cells．
