Abstract:
Objective:To construct a chemiluminescense immune quantification assay based one paired mAbs against complexed prostate specific antigen ( c-PSA).Methods:Six week-old female BALB/c mice were immunized with the commercial c-PSA antigen.After serum titer reaching a platform stage ,the spleen was immunized and fused with mouse myeloma cell lines ( Sp2/0 ) .The hybridoma were screened by indirect ELISA ,and eight generated antibodies were paired to obtain a quantitative analysis of the chemical luminescence.Results:7D6 specifically recognized c-PSA,while 1A10 recognized total PSA(t-PSA).And the paired antibody 1A10/7D6 were determined to successfully construct a chemiluminescense immune response quantitative detection method through the detection of c-PSA standard and clinical serum samples .had,positive samples have statistically significant difference ( P<0.000 1 ) with negative samples.And the correlation coefficient R 2 was 0.97 between our c-PSA quantitative results and that of the Siemens c-PSA chemiluminescense immunoassay kit .The detection linear range was 0.1-100 ng/ml,and the sensitivity was 0.005 ng/ml.Conclusion:The paired monoclonal antibodies specifically detecting c-PSA were generated and a c-PSA chemiluminescense immunoassay were developed in this study .The detection capability of our method was comparable with that of the international commercial kit .
