PURIFICATION METHOD, PURIFICATION KIT, AND SILICA-BINDING TAG USING SAME

摘要

The present invention provides a method for purifying an intended substance, a kit for purifying the intended substance, and a silicon oxide-binding tag for use in the method and the kit. In the present invention, a complex of a silicon oxide-binding tag and a substance is caused to specifically bind to silicon oxide in a solution for binding, to which solution no salt is added, and binding between the silicon oxide-binding tag and the silicon oxide is broken with use of arginine.
