  1. 14 out of 25 strains of biocontrol agent streptomyces showed chitinolytic activity by biological assay. these 14 strains of biocontrol agent streptomyces were detected for chitinase gene using pcr primers derived from the conservative sequence of 17 cloned chitinase genes from streptomyces

    此方法相對于幾丁質酶的傳統生物學檢測，具有更好的準確性和靈敏性；而且與生物學檢測相比，使用分子檢測省時省力。
  2. 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成纖維細胞和mtt法測定表達產物的促細胞增殖作用，發現重組病毒感染家蠶細胞72小時的胞內樣品與正常家蠶細胞裂解物，以及重組病毒感染4天的蠶血淋巴與正常蠶血淋巴均具有相似的促細胞增殖作用，甚至野生型病毒感染的細胞裂解物和蠶血淋巴也有一定的細胞促生長作用，提示家蠶系統本身可能含有能促進細胞生長、類似於egf的細胞因子。
  3. The assay system of the biological activity of lymphotoxin was established using l929 cell as the sensitive target, lt international standard as the positive control and crystal violet staining method to detect viable cell after treated with lt. the best relationship between dosage and effect could be got if the cell seeding density in cell plate was 1. 6 0. 1 104 the dosage of amd was lug / ml, and the starting concentration of dilution in the plate of lt standard was 10 iu / ml with two fold dilution. the credibility of the established system was detected with rhtnfp developed by r & d

    為確定經上述步驟純化后得到的目的蛋自lt 27的生物活性，本研究以l929細胞為靶細胞、淋巴毒素國際標準品為參照，採用結晶紫染色法檢測經淋巴毒素處理后存活的細胞，對淋巴毒素生物活性測定的細胞接種濃度、淋巴毒素標準品板上稀釋的起始濃度和梯度稀釋的倍數、放線菌素d的使用劑量等進行條件實驗后，建立了人淋巴毒素生物活性測定方法。
  4. Expression of a novel human interleukin - 13 in e. coli and its biological activity assay

    13在大腸桿菌中的表達及生物活性分析
  5. The biological activity of purified lt 27 was tested with the assay system, and its biological activity was 2 - 3 107 iu / mg. pro. the cytotoxicity of purified lt 27 was in the same level with rhtnfp and lt international standard. it shows that lt deletion could keep its high cytotoxicity towards tumour cell l929 in vitro after 27 amino acids deleted from its n - terminal

    用建立的淋巴毒素生物活性測定方法對上述純化的淋巴毒素缺失體lt 27的生物活性進行檢測，測得其比活為2一3xl口iu / mg . proo純化的淋巴毒素缺失體lt 27的生物活性與rhtnfp和淋巴毒素國標標準品的生物活性大致相當，表明lt經n端缺失27個氨基酸后仍能保持很高的體外腫瘤細胞毒活性。
  6. Multi - copies insertion transformants were screened on g418 plates. the recombinant protein was proved to have biological activity of hydrolyzing n - carbamoylphenylalanine into phenylalanine through enzyme activity assay. the n - carbamoylase activity of recombinant was 2. 26 and 2. 15 times higher than that of arthrobacter bt801 and dh5a / puc18 - 169

    將hyucdna片段連接到真核表達載體ppic3 . 5k上，經bgl酶切線性化，通過peg法轉化導入畢赤酵母gs115感受態細胞，利用g418抗性篩選得到12個插入多拷貝目的基因的轉化子。
