摘要
Abstract
Objective:Direct competitive enzyme linked immunoassay(dcELISA) was established with enzyme-labeled antigen for detecting shrimp allergic protein in foods.Method:The main allergic protein of shrimp was extracted,and immunized mice to prepare polyclonal antibody,horseradish peroxidase(HRP) labeled antigen was also prepared.The dcELISA method was established for detecting shrimp allergic protein.Results:The results indicated that the LOD of the dcELISA was 3.94ng/mL,linear range of the standard curve was 0.12~128.86ng/mL,and the CV of intra-assay and inter-assay were 6.16% and 2.73% respectively.Recovery ranged from 82% to 98%.Conclusion:The method showed better specificity,sensitivity and stability,applying basis for further development of ELISA kit for shrimp allergic protein detection.关键词
