Abstract
The present invention relates to derivatives of tetanus toxin, a process for their preparation by treating an aqueous solution of tetanus toxin with an aliphatic mono- or dialdehyde, reacting the toxin, before or after the aldehyde treatment, with a denaturing agent in the presence of a compound reducing disulfide bridges obtaining the derivative of the light chain in the presence of the denaturing agent by way of protein-chemical isolation processes and suitably separating it from the denaturing agent, and compositions containing said derivatives.
