应用在大肠杆菌中表达的人骨形成蛋白(human bone morphogenetie protein,HBMP-1)的N端片段作为免疫原,免疫新西兰大白兔,成功地制备了抗人骨形成蛋白的抗血清,经免疫转移电泳证实该抗血清有较好的特异性,用ABC免疫组织化学方法在正常...应用在大肠杆菌中表达的人骨形成蛋白(human bone morphogenetie protein,HBMP-1)的N端片段作为免疫原,免疫新西兰大白兔,成功地制备了抗人骨形成蛋白的抗血清,经免疫转移电泳证实该抗血清有较好的特异性,用ABC免疫组织化学方法在正常和恶性肿瘤骨的石腊切片上检测抗血清效价为1:100~1:1000,免疫组化染色结果表明,HBMP存在于人胎下颌骨新生的骨质和骨细胞中,颌骨骨肉瘤和软骨肉瘤的瘤细胞呈BMP强阳性反应,这一结果表明,骨的生长、形成和骨肿瘤的发生与BMP密切相关。展开更多
目的:探讨凋亡抑制基因Surv iv in在卵巢癌中的表达及其与临床病理资料的关系。方法:采用RT-PCR和W estern b lot检测20例卵巢癌及正常卵巢组织中surv iv ivn基因的表达情况。结果:通过统计分析,发现Surv iv in在卵巢癌组织中表达明显...目的:探讨凋亡抑制基因Surv iv in在卵巢癌中的表达及其与临床病理资料的关系。方法:采用RT-PCR和W estern b lot检测20例卵巢癌及正常卵巢组织中surv iv ivn基因的表达情况。结果:通过统计分析,发现Surv iv in在卵巢癌组织中表达明显高于正常组织。结论:Surv iv in可能在卵巢癌的发生发展中起一定的作用。展开更多

It strongly inhibited lymphocyte proliferation. The results of activity assay, molecular weight determination and histological localization all demonstrated that under stress the immuno-suppressive protein was also generated in intestinal mucosa of rats.展开更多
