Abstract:
Objective:To detect the biological activity of the expression products of the human ?-NGF cDNA in CHO cell line and purified the seperated protein.Methods:Human ?-NGF was transfected with lipofectamine reagent into CHO cell line.The biological activity was analyzed by objection with microscope and the method of MTT.The pure protein was proved by SDS-PAGE analysis.Results:The protein in the culture supernatant of the positive CHO cells transfected with ?-NGF gene could stimulate the growth of PC12 cell line and go into BBB.Conclusion:The target gene expressed successfully in the transfected CHO cell line and had good biological activity.
