ABSTRACT
Objective:To establish quantitative a fluorescence immunochromatographic assay detection method for the heat shock protein 90α(HSP90α)in human serum.Methods: Indirect the technology of fluorescence microshers immunochromatographic assay was used to research fluorescent microsphere activation,ensure optimal testing time,determine linearity range,precision,recovery experiments,testing clinical samples and that sort of thing in the fluorescence immunochromatographicassay experiment.Results: In all the reaction conditions,it was determined that the optimal teaction time was 5 minutes,and in the best line range (0.39-100 ng/ml) precision quality control materials of high recovery (30 ng/ml) Intra-assay CV was 8.14%;quality control materials of low recovery (10 ng/ml) Intra-assay CV was 9.26%.With high,medium and low recovery of serum recovery was 100.56%,99.76%,94.1%,separately.Foreign kit(ELISA) for detection of 40 cancer patients clinical serum,the result showed that the correlation was 0.968 5.Conclusion: Establishing the method initially quantitative fluorescence immunochromatographic assay for the heat shock protein 90α(HSP90α)in human serum have high performance and linear,clinic accordance rate also can satisfy the demand of clinic quantitative detection,and will improve hopeful to applied to clinic after apprroved.
