PROBLEM TO BE SOLVED: To provide a separation membrane for obtaining an analysis solution (analyte sample) from which a substance interfering with detection of a trace component is removed during clinical proteome analysis. A separation membrane having an asymmetric structure. By using this separation membrane, an interfering substance having a high molecular weight is efficiently removed. The solution obtained by this separation membrane is used for protein analysis such as mass spectrometry, electrophoresis, liquid chromatography, etc., and enables highly sensitive analysis.
