细胞或组织的萎缩

The ELISA titre was 1:2000.By cell fusion, 46 hybridoma cell lines were screened,and 10 lines were cloned with limited dilution method.16 lines secreting anti-bFGF monoclonal antibody were been developed, and 2 lines targeted fusion protein. Sensitive ELISA and dot-ELISA for bFGF was developed with this mAb. The detection limit of them were 0.1 ng/well and 0.5 ng/well. The expression level of anti-bFGF mAb by different rebuilt engineering cells were identified by western blot and to direct rebuild recombiment engineering cell. The dose and character of anti-bFGF mAb inhibiting bFGF biology activity were searched by 3T3 cell line. Searching 20 tissue of liver cancer, liver cancer cell lines and general tissue of liver, finding bFGF were highly expressed in tissues of liver cancer and liver cancer cell lines. Affinity chromatography purifying bFGF was set up by mAb binging CNBr-pepharose 4B, and the purification was 95%. We found that the titer of anti-bFGF antibody was very high in serum of neuropathic amyotrophia.

应用细胞融合制备46株杂交瘤，对其中10株进行克隆化，获得bFGF特异单抗16株，2株针对融合蛋白；应用该单抗建立了0.1ng/孔灵敏度的ELISA，0.5ng/孔敏度的斑点ELISA；用Western-blotting鉴别了经改造不同工程菌蛋白表达，指导重组工程菌改造；用3T3细胞培养研究了单抗抑制bFGF生物学活性的剂量和特点；合作研究了20例肝癌、肝癌细胞株和正常肝组织，发现前者bFGF高表达；应用单抗偶联CNBr-sepharose 4B建立了小量免疫亲和层析纯化bFGF，纯度达到95%；发现神经性肌萎缩患者血清中含有高滴度的bFGF抗体，已有10多家单位引用单抗或进行合作。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
