The immunocompetence and cell toxicity of the samples toward Tand B lymphocyte were determined.

并且测定了样品对T、B淋巴细胞的免疫活性和细胞毒性。

Objective To further testify the value of applying purified protein derivative(PPD) of tuberculin in monitoring the immunocompetence.

目的进一步证实P P D 实验在监测结核免疫力中的应用价值。

After two rounds of panning, 21 positive plaques were selected each round at random respectively. ELISA assay was used to examine the immunocompetence of each clone.

每轮随机挑取蓝色噬菌斑各21个，用ELISA方法检测其抗原性，并对其反应性较好的阳性克隆进行测序。

The mechanism of tumor dormancy is related to hindrance of angiogenesis, oncogene and antioncogene, immunocompetence, proliferation cycle, signal conduction and so on.

其发生机制可能与肿瘤血管生成受阻、癌基因与抑癌基因、宿主免疫状态、肿瘤细胞增殖周期及信号传导有关。

The immunocompetence of low molecular weight heparin(LMWH) derived from low anticoagulant activity heparin(LAAH), a by-product in commercial heparin production, was studied.
