Abstract
The purpose of the present invention is to provide a method for evaluating the clogging of a filtration membrane with a protein-containing solution, including the steps of: a) passing a protein-containing solution through a filtration membrane, b) after the step a), obtaining a filtration membrane cross-section from the filtration membrane, c) treating the protein-containing solution before the step a), the filtration membrane before the step b), or the filtration membrane cross-section after the step b) with at least one stain specific to a protein aggregate, and d) confirming the presence of the protein aggregate in the filtration membrane cross-section.
