Title: Innovations of Chang-Kwon Ko in Collagen Separation
Introduction
Chang-Kwon Ko is a notable inventor based in Seoul, South Korea. He has made significant contributions to the field of collagen extraction and processing. His innovative methods have the potential to impact various industries, including pharmaceuticals and cosmetics.
Latest Patents
Chang-Kwon Ko holds a patent for a method of separating collagen from various animal tissues for producing collagen solutions and products. This method involves processing porcine tissues to achieve the appropriate form and size for acid treatment. The acid treatment is repeated with pepsin to separate type I or II collagens. The separated collagen undergoes salt treatment for fractionation and ethanol treatment to obtain 5% to 10% of collagen from the initial tissue weight. The prepared tissues are then processed to separate collagen through a specific collagen separating process. The final product preparation involves treating a collagen solution with a predetermined concentration under neutral conditions at low temperatures, followed by overnight treatment at temperatures between 30 to 35°C. The concentrated collagen is then dissolved in a refrigerated weakly-acidic solvent or phosphate buffered saline (PBS), resulting in a collagen concentration of 1 to 5 mg/mL.
Career Highlights
Chang-Kwon Ko is currently associated with Sewon Cellontech Co., Ltd., where he continues to develop and refine his innovative methods. His work has garnered attention for its practical applications in producing high-quality collagen products.
