Detoxification of Crystalline Botulinum Type A Toxin

[摘要] Botulinum Type A toxoid has been prepared from crystalline toxin by the addition of formaldehyde. The most active preparation consisted of one component electrophoretically, immunized mice in a dose containing 0.01γ of toxoidnitrogen and was 2400 times more active antigenically than crude toxoid on the basis of nitrogen-content.
