Title: Purification of protein
Inventor: KAWAHATA YOSHIAKI
IPC: A61K35/14
Filed: 1984-06-27
Abstract: PURPOSE:To purify various proteins, rapidly, easily, in high yield, at a low cost, by using a cartridge-type adsorbent produced by filling the space in a cellulose mesh with an adsorption carrier, and filling the obtained sheet in a container. CONSTITUTION:The spaces of a cellulose mesh is filled with an adsorption carrier (e.g. an ion exchange resin), and the obtained sheet is filled preferably in the form of spiral in a container. Proteins (e.g. urokinase, kallikrein, lysozyme, blood coagulation factor, albumin, etc.) are purified by using the obtained cartridge- type adsorbent. A large amount of proteins can be purified in a short time, and the recovery reaches >=90%. Since the solution can be passed through the cartridge-type adsorbent at a high speed, it is especially useful when used in the treatment of a large amount of specimen such as the recovery of urokinase, kallikrein, etc. existing very little in urine.
