Abstract
It is an object of the present invention to provide a method for eluting an adsorbed protein that suppresses a decrease in protein adsorption ability, in a method for purifying a protein using a protein-adsorbing porous membrane.The present invention provides a method for purifying a protein, comprising an adsorption step and an elution step, wherein in the elution step, at least one eluent is passed in the opposite direction with respect to the direction of the passage of a stock solution containing an adsorption target protein, in the adsorption step.
