title: Generation and characterization of monoclonal antibodies against botulinum neurotoxin type A (BoNT/A).
abstract: OBJECTIVE
  To generate the monoclonal antibodies(mAbs) against botulinum neurotoxin type A (BoNT/A).
  
  
  METHODS
  BALB/c mice were intraperitoneally immunized with purified BoNT/A-Hc, and the splenocytes of immunized mice were fused with myeloma cells Sp2/0. Hybridoma cells were screened by indirect ELISA and monoclonal hybridoma cells was obtained using limited dilution.
  
  
  RESULTS
  Three hybridomas, named 4A8, 2F7 and 4F2, producing the mAbs against BoNT/A, were successfully established, and the titer of ascitic mAbs ranged from 1x10(-4) to 1x10(-6). Identification of subclass showed that all the produced mAbs belonged to IgG1. 4A8 and 4F2 were stable in secreting anti-BoNT/A mAbs through three-month continuous culture and showed high specificity to recombinant BoNT/A-Hc and native BoNT/A.
  
  
  CONCLUSIONS
  Anti-BoNT/A mAbs we generated have high specificity, which laid the foundation for the immunological detection of BoNT/A and clinical treatment of botulism in the future.
