Abstract : liquid - phase chromatographic instruments and electric conductivity detectors produced by two factories were connected and adjusted for the purpose of their smooth operation . in addition , the optimum working conditions for detecting some inorganic anions in drinking water were determined 文摘:对来自2个厂家的液相色谱仪和电导检测器进行连接、调试,使其能正常运行,并确定检测饮水中某些无机阴离子的最佳工作条件。
Experiment shows that the antigen extracted by autoclave is best for dot - ppa - elisa . applying the x2 test , optimal concentration of antigen was determined , and the optimum dilution of enzyme hrp - spa was 1 : 10 . the high specificity of dot - ppa - elisa was proved by the specific blocking test , and also by the cross - reaction test in which the diaphragm does not react with the antibodies against salmonellosis , pasteurellosis , chlamydiosis , hcv , ppv , brucellosis , erysipelas suis , colibacillosis , prv 试验中对多种方法提取的诊断抗原进行了比较、筛选;确定了dot - ppa - elisa的最佳工作条件;测定了st - 171株的免疫猪血清抗体及c群、 2型人工感染猪血清抗体效价,并初步确定了该方法的阳性标准。
To ensure optimal conditions , the detector contains a heating device , a magnetic stirrer , and a small refrigeration device . all of these devices are controlled by programmable controller . liquid crystal touch screen communicated with programmable controller , provides a friendly man - machine interface , which make the operation more simple and convenient 为确保酶电极的最佳工作条件,系统由加热、磁力搅拌、制冷等装置组成,在可编程控制器的控制下完成检测工作,并配以液晶触摸屏,提供良好的人机界面,使操作更加简单方便。
Different kinds of salmonella antigens have been tried and an improved heat - extracted antigen was used as the diaphragm antigen . the optimum condition of dot - ppa - elisa was determined . the antibody positive standard of salmonella infection was established as 1 : 32 , and the positive standard of protecting pigs from salmonella infection as 1 : 512 研究中对多种方法提取的沙门氏菌抗原进行了筛选,选取了特异性良好的抗原;确定了dot - ppa - elisa的最佳工作条件;初步确定了感染仔猪副伤寒的dot - elisa抗体阳性标准为1 : 32 ,猪只抵御副伤寒感染的dot - elisa抗体保护标准为1 : 512 。
