Abstract:
Objective To synthesize and identify artificial antigens of lung elastin degradation peptide and for the purpose of preparation of COPD test.Methods The artificial antigens were synthesized by Sulfo-SMCC and KLH.The complete antigens were identified by ultraviolet spectrum and SDS-PAGE.Immunize Balb/c mice was used to prepare antibody.The antiserum activity was evaluated by indirect competitive ELISA.Results The artificial antigens were identified by ultraviolet spectrum and SDS-PAGE. The protein concentration was 1.181 mg/mL.The titer of antiserum was 1∶64 000,and IC50 was 13.7 ng/mL.The antiserum had no cross-reaction with nonsense peptide.Conclusion The artificial antigens were acquired successfully,which had good immunoge-nicity.The results have laid basis for COPD test.
