| 摘要 |
The present invention provides a method for purifying a protein, includes the step of: contacting a fusion protein of a first protein and a second protein with a bivalent cation-containing solution, the fusion protein being adsorbed to a silicon oxide-containing substance, the first protein being capable of binding to the silicon oxide-containing substance in a solution containing 0.1M sodium chloride. With this arrangement, it is possible to easily produce large quantity of proteins which are high in purity without sacrificing activity of the proteins. |
