鸭疫里氏杆菌双抗体夹心ELISA检测方法的建立
Establishment of a double antibody sandwich ELISA for the detection of Riemerella anatipestifer
摘要
Abstract
The aim of the present study was to develop a rapid and accurate method for the detection of Riemerella anatipestifer based on a double antibody sandwich ELISA. Purified polyclonal antibody against serotype 1 R. anatipestifer was used as a capture antibody, while purified monoclonal antibody 5G7 was used as a detection antibody. The optimal conditions for the ELISA were as follows:polyclonal antibody with 184 ng per well was added to coat overnight,the plate was blocked by 100 mL/L neonatal calf serum for 2 hours at 37℃ ,the incubation times for detection antigen,monoclonal antibody and second labeled an- tibody were 1 hour at 37℃for each,the value of D450nm was obtained after 20 min coloration. This method has no cross-reaction with poultry-origin Pasteurella multocida, Escherichia coli and Salmonella, and its minimum detectable limit was 104 CFU/mL. The sensitivity of the method was 100% ,and the coincidence between bacterial isolation method and the double antibody sandwich ELISA was 85.2M. Therefore,this study provides a rapid, specific and sensitive detection method for R. anatipestifer.关键词
