Abstract:
Objective:To develop a sensitive,rapid,simple gold immunochromatography assay for human cardiac troponin I(cTnI).Methods:The cTnI was used to immunize Balb/c mice by route method.The spenocytes were fused with SP2/0 myeloma cell lines.Six hybridoma cell lines,secreting stably McAbs to cTnI antigen have been obtained and screened.The 3F10 was coupled with colloidal golds,the 3A7 biotinylated.Streptavidin was coupled with the nitrocellose strip to prepare an test apparatu.According to red line in nitrocellose,thus can analysis the results.Results:The sensitivity of cTnI measured by this apparatus was 0.4 ng/ml.The 30 patients with acute myocardial infarction(AMI)were detected for cTnI by this apparatus and by the product of PBM Co USA as standard.The coincidence rate of both two assays was 93.6%. Conclusion:This method is a sensitive,specific simple and rapid assay.
