In this paper, purification of growth hormone receptor from ovine liver and identification of its biochemical character have been done.Firstly, by homogenizing, triturating, high-speed centrifuging, hypervelocity centrifuging and sucrose density grade centrifuging cell membrane of ovine liver was separated and its electron microscope slice wasprotein was disL~olved with TritonX-100,amL-thebinding activity between cell membrane or membrane protein and ~I-hGH using RRAwas measured, perfect saturated curve wasgained. Thirdly, specific binding of GILR protein was measured ,by SDSPAGE, its molecular weight is about 1 19KD.

本研究采取新鲜羯羊肝脏，匀浆、研磨，经高速离心，超速离心和蔗糖密度梯度离心，分离肝脏质膜，得到肝脏质膜的电镜切片：其次，用去垢剂TritonX-100增溶膜蛋白，利用放射受体分析法，测定细胞膜及膜蛋白与~(125)I-hGH的结合活性，均得到理想的饱和曲线；再次，将两点结合试验法与凝胶层析法结合检测到特异结合物，然后，经SDS-PAGE电泳分析，纯化后的样品呈现一条带，与标准分子量比较，得出分子量为119KD。
