In particular, soluble recombinant Clostridium botulinum type A toxin proteins are provided. Methods which allow for the isolation of recombinant proteins free of significant endotoxin contamination are provided. The soluble, endotoxin-free recombinant proteins are used as immunogens for the production of vaccines and antitoxins. These vaccines and antitoxins are useful in the treatment of humans and other animals at risk of intoxication with clostridial toxin.Type: GrantFiled: March 16, 1995Date of Patent: July 6, 1999Assignee: Ophidian Pharmaceuticals, Inc.Inventor: James A. Williams

Patent number: 5904922Abstract: Antivenoms to snake, spider, scorpion and jelly fish venoms are produced for treatment of humans and animals, and for analytical use. Polyvalent antivenoms are produced containing immunoglobulin which is greater than fifty percent venom reactive. Purified polyvalent antivenom is derived from a first polyvalent antivenom having two or more monovalent subpopulations, and purified such that greater than fifty percent of the monovalent subpopulations are recovered by weight. The antivenoms can be horse or avian such as chicken antivenom. Chicken antivenom is obtained using a whole venom that is not glutaraldehyde pretreated, and the antivenom contains yolk immunoglobulin. Antivenoms are purified with an antigen matrix containing a single whole venom or a plurality of whole venoms covalently attached to an insoluble support such as aldehyde-activated agarose. Preferably, the whole venoms forming the plurality of whole venoms are selected from the four whole venoms of C. atrox, B. atrox, C. adamanteus and C.Type: GrantFiled: May 16, 1995Date of Patent: May 18, 1999Assignee: Ophidian Pharmaceuticals, Inc.Inventor: Sean B.
