• The expression mixture were eletrophoresized by sds - page , revealing a specific 56 kd protein in bl21 expression system , which is of the same size in expectation . a colorimetric assay for measuring cholesterol oxidase showed the cholesterol oxidase activity of the expression product
  其结果经sds ? page分析表明：以pet - his为表达载体，大肠杆菌bl21 ( de3 ) plyss为宿主菌的重组表达系统表达出约56kd的特异蛋白，蛋白大小与预期结果相一致。
• They were capable of detecting 50 pg of purified total rna by a colorimetric assay and 5 pg by a chemiluminescent assay . the nonradioactive probe produced with pcr amplification were particularly suitable for practical diagnosis , as they are sensitive and can be rapidly prepared in large quantities . the two assay methods were 260 times and 26 times as sensitvity as r - page respectively
  利用含pstvd单体的pgem - 7z质粒，通过pcr扩增技术，用生物素标记制备cdna探针，进行杂交反应检测pstvd ，其中通过化学颜色反应进行判读灵敏度可达到50pg ，而用化学发光反应进行判读灵敏度可达到5pg ，分别是r - page检测灵敏度的260倍和26倍。
• Biological activity was determined by egf dependent balb / c 3t3 cell line and with mtt colorimetric assay . extracts of the recombinant virus - infected and mock - infected cells , haemolymph of the recombinant virus infected and mock - infected silkworm larvae could all support the proliferation of balb / c 3t3 cell . this phenomena implied that there were some egf - like growth factors in the haemolymph of normal silkworm larvae , which could enhance the proliferation of the cell line
  用小鼠balb c3t3成纤维细胞和mtt法测定表达产物的促细胞增殖作用，发现重组病毒感染家蚕细胞72小时的胞内样品与正常家蚕细胞裂解物，以及重组病毒感染4天的蚕血淋巴与正常蚕血淋巴均具有相似的促细胞增殖作用，甚至野生型病毒感染的细胞裂解物和蚕血淋巴也有一定的细胞促生长作用，提示家蚕系统本身可能含有能促进细胞生长、类似于egf的细胞因子。
