The production and evaluation of monoclonal antibodies to Clostridium perfringens type D epsilon toxin.

The production of five monoclonal antibodies to the epsilon prototoxin of Clostridium perfringens is described. All five monoclonal antibodies located three proteins in a trypsinized preparation of epsilon prototoxin. These proteins were located at 37.6 kDal, 35.6 kDal and 33.7 kDal by Western blots. Two of the monoclonal antibodies, M26/2 and M27/12, neutralized epsilon toxin in the mouse lethality assay. Four of the five monoclonal antibodies are considered suitable as reagents to detect epsilon toxin in assay procedures.
