Latest Patents

Yeong Duk An holds a patent for a method of producing botulinum toxin. This method involves treating a culture of a botulinum toxin-producing strain with acid to precipitate the toxin. Following this, a buffer is added to the precipitated toxin, which is then treated with a protease inhibitor and nuclease to extract the botulinum toxin. The extracted toxin undergoes further treatment with acid to precipitate it again, and the final product is purified using anion exchange chromatography. This process allows for the production of high-purity botulinum toxin through a simplified method. The resulting toxin has enhanced local action and reduced systemic circulation, increasing safety for various medical applications.
