Therapeutic antibodies provide important tools in the "medicine chest" of today's clinician for the treatment of a range of disorders. Typically monoclonal or polyclonal antibodies are administered in large doses, either directly or indirectly into t

Clostridium botulinum type A toxin is the most prevalent cause of naturally occurring outbreaks of human botulism in the world. The active dichain neurotoxin molecule is composed of a heavy chain (H-chain) of ~100 kDa with the carboxy-terminal end co

Conventional capture (“Sandwich”) ELISAs equally detect denatured inactive and native active botulinum type A toxin. Light chain endoprotease activity assays also fail to distinguish between various inactive molecules including partially denature

Botulinum type A toxin (BoNT/A) is defined by its specific endopeptidase cleavage of SNAP25 between Gln(197) and Arg(198) under reducing conditions. The neurotoxin is widely used for therapeutic or cosmetic purposes, but should not contain other toxi

Botulinum neurotoxins contain proteases that cleave specific intra-neural proteins essential for neurotransmitter release. Toxin types A, E and C1 intra-cellularly cleave SNAP25 resulting in a flaccid paralysis. As a consequence, various different en

Clostridium botulinum produces the most potent known toxins, with seven distinct serotypes currently defined (A-G). These toxins can cause a life threatening systemic toxicity whether through natural causes such as food poisoning, infant botulism, wo

The digestion of ovine antiserum under acidic conditions (pH 3.5) by pepsin is highly effective at reducing all unwanted serum components to low molecular weight (< or =13 kDa) fragments while leaving the approximately 100-kDa F(ab')(2) intact. The p

Asimple process for the manufacture of polyclonal F(ab′)2 fragments that might be adopted for the facile preparation of antivenoms is described. The production of polyclonal F(ab′)2 fragments from serum commonly involves the initial purification

Enzyme-cleaved antibodies are used widely for the treatment of envenoming. Such products should comprise only 'highly pure' immunoglobulin fragments since Fc or other contaminating protein fragments or their aggregates may lead to side effects. The d

The frequency of mass bee attacks has dramatically increased in the Americas following the introduction and spread of the aggressive Africanized 'killer' bee (Apis mellifera scutellata). As yet no specific therapy is available, which led us to develo
