Abstract: The objective of this work is to prepare cystain C antibody and establish the chemiluminescence detection method for the early diagnosis of renal damnification. Cystatin C monoclonal antibody was prepared through chemical synthesis of cystain C polypeptide,then competitive inhibition assay was used for preliminary screening of paired antibody,and chemiluminescence immunoassay detection method of cystain C was established. Totally,39 strains of cystatin C monoclonal antibody cells were obtained,and paired antibody was screened. By analyzing the linear range,minimum detection limit,precision,accuracy and other performance evaluation analysis,chemical luminescence detection method for detecting cystatin C was established,with linear range of 50--20 000 ng/mL and the minimum detection limit of 3 ng/mL. Conclusively,cystatin C paired antibody was prepared and chemiluminescence detection method was established successfully,which provides a new detection technique and method for early renal damnification.
