Latest Patents

Stokke's latest patents focus on a novel process for the production of diphtheria toxin. The method involves fermenting a microorganism strain capable of producing diphtheria toxin using glucose as a carbon source. This process includes adding glucose to a growing culture, which maintains microorganism growth effective for supporting diphtheria toxin production. The purification of the diphtheria toxin is achieved by contacting a toxin-containing preparation with an ion exchange matrix, followed by eluting a fraction containing the toxin. The eluate is then applied to a hydrophobic matrix, and a fraction containing the toxin is eluted.
