<p>A novel aptamer against IgG, use of the aptamer and others. More specifically, an aptamer capable of binding to the Fc segment of IgG (e.g., human IgG); a complex comprising the aptamer and a functional substance bound to the aptamer (e.g., an affinity substance, a labeling substance, an enzyme, a medicinal substance, a toxin, a drug delivery medium); a solid support having the aptamer or the complex immobilized thereto; a device for medical purposes comprising the solid support; a method for purification of an antibody, comprising holding an IgG antibody by adsorption on the solid support and eluting the adsorbed IgG antibody with an eluent; a process for producing a purified antibody, comprising preparing an IgG antibody and purifying the IgG antibody using the solid support; and others.</p> |
