Abstract
Fibrous connective tissue for surgical implantation is made substantially antigen-free by contact with one or more extraction agents. Solutions or mixtures of molecules having bipolar regions act as antigen removing permeation enhancers. Cationic, anionic, non-ionic or amphoteric surfactants are suitable bipolar permeation enhancers. One or more extraction agents can be combined to form extraction mixtures.
