In this paper monoclonal antibody specific to motoneuronotrophic factor was used to study the immunohistochemical distribution of the motoneuronotrophic factor in embryos(E13,14,18and 21 days)and neonates(P1,3,6,14 and 21 days)of SD rats.

• 用免疫组织化学ABC法检测了SD大鼠胚胎（E13、14、18、20d）和幼鼠（P1、3、6d；2周、3周）体内运动神经元诱向因子（MNTF）的分布。
