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.

The results showed that plenty of the purified DPV virions were obtained after the cell lysate was condensed by 5-fold by ultrafiltration,and the concentrated DPV fluid was ultracentrifuged with 300g/L sucrose cushion method and 300-600g/kg sucrose density gradient centrifugation methods.

结果显示，用切向超滤法将病毒培养物浓缩为原体积的1/5后，再采用300g/L蔗糖垫底超速离心和300～600g/kg蔗糖密度梯度离心的方法进行纯化，可获得大量的纯化病毒粒子。

The recombinant viruses, with the gene of reference RV strain VP2, field strain T114 VP6 and T73 G1-serotype VP7, respectively, co-infected Sf9 cell at a multiplicity of infection of 0.5. Harvested the supernatants of culture when the cells were lysed fully (about 7-10 days), or harvested cells before cell lysates (about 4-5 days after infection) and then treated the cells with lysing solution. The supernatants of and cell lysates were ultracentrifuged twice with 40% sucrose cushion at 93 000g, and the sediment products were harvested with TNC buffer. The purified VLPs samples were separated by SDS-PAGE, and then stained by Coomassie blue and silver nitrate and detected by Western blot to analyze the composition of VP2, VP6 and VP7 and their specificity. The morphologic structure of recombinant VLPs was detected by EM.
