摘要
目的:sHLAⅠ可预测器官移植排斥反应及监控某些疾病。为了介绍sHLAⅠ类抗原定量检测技术及中国人sHLAⅠ正常值。方法:采用ELISA双抗夹心法,以W6/32mAb包被酶标板,加被检血清,再加β2mHRP及底物显色。以不同浓度sHLAⅠ标准品的结果绘出标准曲线并测定113例正常人sHLAⅠ含量。结果:ELISA法可以准确定量测定血清中sHLAⅠ,中国人sHLAⅠ正常值为78927±50632ng/ml。结论:ELISA法检测sHLAⅠ具有特异、敏感及重复性。
Objective:sHLA Ⅰ antigens may predict the onset of rejection after organ transplantation and monitor some diseases. The method of quantification of sHLA Ⅰ antigens and its normal level in Chinese were reported. Methods:Sandwich ELISA assay was used. After microtiter plate coated by W6/32 mAb, serum was added, followed by incubation with anti β 2m HRP and the color development. Standard curve was obtained by quantification of sHLA Ⅰstandard reagent in series dilution. The amount of sHLA Ⅰantigens was examined in 113 normal healthy volunteers. Results: sHLA Ⅰ antigens can be exactly quantificated by sandwich ELISA assay. The level of sHLA Ⅰ antigens in normal individual is 789.27±506.32 ng/ml. Conclusion: Sandwich ELISA assay is special, sensitive and reproducible for sHLA Ⅰ antigens, and the results can be compared each other only when reagents and protocols are the same.
