The results of blocking test to four serotypes were positve when relative antigens were coated 各血清型鸭疫里默氏杆菌抗原阻断结果阳性。
05 . 02 wear preventive properties of lubrication greases using the ring and block test machine in oscillating motion , test for 在震荡运动中用润滑剂耐热耐压试验机测定润滑脂的耐磨损特性的试验
05 . 03 test method for evaluating thin film fluid lubricants in a drain and dry mode using a pin and v - block test machine 在排水和干燥模式下利用针式和v -块式试验机评价薄膜流动性润滑剂性能的测试方法
Standard test method for evaluating thin film fluid lubricants in a drain and dry mode using a pin and vee block test machine 使用销钉和v形块试验机以排水和干燥方式评定薄膜流体润滑油的标准试验方法
The high specificity of dot - elisa was proved by the specific blocking test and the cross - reaction te st in which the diagnostic diaphragm did n ' t react with the positive serum against ibdv , ibv , eds - 76 , pox , ibv , iltv , salmonellosis jc . both the test within batch and the test among batches proved the method or the diagnostic diaphragm was stable . stored at 4c for at least 6 months , the diagnostic diaphragm ' s sensitivity and specificity did n ' t change 阻断试验和交叉试验表明快诊膜具有良好的特异性:不与马立克、法氏囊、鸡痘、鸡传支、鸡传喉、鸡减蛋综合症、鸡传鼻、鸡沙门氏菌等阳性血清反应。批内和批间重复性试验表明该法重复性良好。诊断膜片4至少可保存6个月,其特异性、灵敏性不变。
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。
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 did n ' t react with the antibodies against pasteurellosis , streptococcosis , colibacillosis , chlamydiosis , hcv , ppv , brucellosis , prv and foot - mouth disease . the diaphragm has good sensitivity and could detect some salmonella - positive test serum which has been diluted to 1 : 2048 . stored at 4 for at least 6 months or at 10 - 25 " c for 4 months , the sensitivity and specif icity of the diaphragm did n ' t change , so it has good stability 本研究制备的诊断膜片特异性强:不与猪衣原体病、猪口蹄疫病、猪大肠杆菌病、猪布氏杆菌病、猪瘟、猪伪狂犬病、猪细小病毒病、猪巴氏杆菌病、猪链球菌病的阳性血清发生交叉反应;诊断膜片具有良好的敏感性,能够检测到1 : 2048稀释的动物试验阳性血清;膜片的保存期长,在10 25可保存4个月、 4条件下至少可保存6个月其灵敏度不变。
