  • Publication number: 20110105940
    Abstract: A method for quantification of a titer of a neutralizing antibody to a neurotoxin is disclosed. The method comprises the steps: (a) mixing a standard sample containing a fixed amount of a neurotoxin and a test sample containing a neutralizing antibody to said neurotoxin; (b) administering the mixture obtained in step (a) into the muscle of a non-human mammal; (c) applying electric stimulus to said non-human mammal; (d) measuring a compound muscle action potential (CMAP) due to contraction of the muscle of said mammal by application of electric stimulus with an electromyograph; and (e) analyzing CMAP amplitude data obtained in step (d) for an extent of decrease in amplitude by a non-neutralized neurotoxin to thereby quantify a titer of the neutralizing antibody contained in the test sample.

  • Publication number: 20060153877
    Abstract: An M toxin of type A botulinum toxin (HA-negative substance) and a mixture of L toxin and LL toxin (HA-positive substance) are compared and examined in inhibitory action for neuromuscular transmission and therapeutic index. As a result, it is found that M toxin of type A botulinum toxin has characteristics of: 1) having an excellent inhibitory action for neuromuscular transmission; 2)showing a high therapeutic index; 3) showing a low antigenicity and 4) suffering from little reduction in efficacy even after repeatedly administered, compared with the mixture of L toxin and LL toxin.
