WebThe standard of treatment for botulism, equine antitoxin, is a foreign protein with associated safety issues and a short serum half-life which excludes its use as a prophylactic antitoxin and makes it a less-than-optimal therapeutic. Due to these limitations, a recombinant monoclonal antibody (mAb) product is preferable. It has been shown that combining … WebAt one-half of this volume of added base, called the half-equivalence point, enough has been added to neutralize half of the acid. Since half of the acid reacted to form A–, the concentrations of A– and HA at the half-equivalence point are the same. Therefore, at the half-equivalence point, the pH is equal to the pKa. Since a-
