Description

Obiltoxaximab is a monoclonal antibody specifically engineered to neutralize the protective antigen of *Bacillus anthracis*, the causative agent of anthrax. This product matters as a critical component in the development and production of therapeutic countermeasures for biodefense and public health preparedness. It is essential for pharmaceutical manufacturers, government agencies, and research institutions focused on advanced infectious disease treatments and prophylactic solutions. Obiltoxaximab CAS NO 1351337-07-9 represents a high-purity, biologically active ingredient for formulation into final drug products.

Application

• Active Pharmaceutical Ingredient (API) in the formulation of anthrax antitoxin therapeutics.
• Key reagent in biodefense research and the development of medical countermeasures.
• Critical component for government stockpiling programs aimed at public health emergency preparedness.
• Reference standard in bioanalytical method development and quality control testing.
• Use in preclinical and clinical research studies investigating novel anthrax treatment protocols.
• Essential material for contract development and manufacturing organizations (CDMOs) serving the biopharma sector.
