Epsilon protoxin was purified from culture supernatants of Clostridium perfringens, strain 34 (type B) (ATCC ® 3626™). The protein is suitable for western blots or can be treated with trypsin to generate the active toxin for cytotoxicity assays.

Each vial of NR-856 contains approximately 0.25 mg of epsilon protoxin suspended in 10 mM phosphate buffer (pH 7.4).

NR-856 reacts with polyclonal IgG antibody produced by immunization of rabbits with peptides that correspond to distinct internal regions of the full-length epsilon toxin (BEI Resources NR-865).
