Abstract
The present invention relates to a protein-binding material including a mesoporous silica and a method for selectively separating and purifying using the protein-binding material. More specifically, the present invention relates to a method of preparing a magnetic mesoporous silica responding to a magnetic field by adsorbing a precursor of a transition metal or its ion, such as an iron (Fe) precursor, onto a mesoporous silica, and to a protein-binding material prepared by coating the surface of the magnetic mesoporous silica with a transition metal or its ion so as to be capable of binding to a specific protein labeled with histidine, and also to a method of selectively separating and purifying a specific protein using the protein-binding material.
