神经生长因子(Nerve Growth Factor,NGF)是最早发现的神经细胞调节因子。自1987年以来,我们对NGF 的制备和应用进行了较系统的研究,现将我科用人体胎盘制备 NGF 及其活性测定的结果报告如下。1 材料和方法1.1 试剂和 NGF 制备1.1.1 试剂:羧甲基纤维素 CM_(52)。美国 Whatma 公司产品;DMEM 培养基,GIBCO 产品;等电点和分子量
Nerve growth factor (NGF) is the earliest discovered neural cell regulator. Since 1987, we have a more systematic study of the preparation and application of NGF, now our department of human placenta preparation of NGF and its activity determination results are reported as follows. 1 Materials and methods 1.1 Reagents and NGF Preparation 1.1.1 Reagents: carboxymethyl cellulose CM_ (52).
