Development and Characterization of Monoclonal Antibodies to Botulinum Neurotoxin Type E

Immunological Characterization and Neutralizing Ability of Monoclonal Antibodies Directed Against Botulinum Neurotoxin Type H

BACKGROUND Only Clostridium botulinum strain IBCA10-7060 produces the recently described novel botulinum neurotoxin type H (BoNT/H). BoNT/H (N-terminal two-thirds most homologous to BoNT/F and C-terminal one-third most homologous to BoNT/A) requires antitoxin to toxin ratios ≥1190:1 for neutralization by existing antitoxins. Hence, more potent and safer antitoxins against BoNT/H are needed. M...

Cloning, Expression and Purification of Clostridium botulinum Neurotoxin Type E Binding Domain

Immunological characterization of Clostridium butyricum neurotoxin and its trypsin-induced fragment by use of monoclonal antibodies against Clostridium botulinum type E neurotoxin.

We examined the reactivities of Clostridium butyricum neurotoxin to nine monoclonal antibodies against Clostridium botulinum type E neurotoxin which recognize the light chain or the amino-terminal half (H-1 fragment) or the carboxyl-terminal half (H-2 fragment) of the heavy chain of botulinum neurotoxin. Butyricum neurotoxin and its derived chains did not react to two of four monoclonal antibod...

Sheep Monoclonal Antibodies Prevent Systemic Effects of Botulinum Neurotoxin A1

Botulinum neurotoxin (BoNT) is responsible for causing botulism, a potentially fatal disease characterized by paralysis of skeletal muscle. Existing specific treatments include polyclonal antisera derived from immunized humans or horses. Both preparations have similar drawbacks, including limited supply, risk of adverse effects and batch to batch variation. Here, we describe a panel of six high...

Production and Partial Characterization of Monoclonal Antibodies to Leishmania

Background: Monoclonal antibody technology allows identification of amastigote-specific antigen in human tissue biopsies and search for a suitable vaccine candidate, which may induce a long lasting immunity. Objectives: Production and partial characterization of seven monoclonal antibodies against Leishmania tropica promstigotes. Methods: Seven murine monoclonal antibodies of the IgG isotype we...
