Abstract:

A monoclonal antibody against fumonisin B1 (FB1) was developed and applied to establish rapid immunology detection method of FB1.FB1 was successfully conjugated with BSA and OVA using EDC,respectively.Hybridoma cell line secreting monoclona antibodys (mAbs) against FB1 was produced by fusing murine SP2/0 cells with the spleen B cells of BALB/c mice which was immunized with FB1-BSA for four times,every four weeks at a time.The mAbs against FB1 were obtained by inducing ascites in the mice body.The affinity,titer,substype and sensibility of the mAbs were assayed with ELISA.Furthermore,the mAbs were preliminarily applied in immunology detection of FB1.The mAbs against FB1 whose substype was tested as IgG3 were secreted by hybridoma cell line (2E11-H3).The working concentration of the mAbs was 1∶6.0×104,affinity constant was 7.98× 1010 L•mol-1,IC50 was 43.65 ng•mL-1.The cross reaction ratios with Fumonisin B2 and B3 were accordingly 385% and 72.4%,while none with other analogues and carrier protein.The recovery rate of sample was among 85.85%-114.07%,the average was 98.81% and the coefficient of variation was 10.11%.The monoclonal antibody against FB1 with high affinity,specificity and sensibility was produced and preliminarily applied in immunology determination of FB1.
