【Task】 The present invention provides a hollow fiber membrane separation membrane that can easily concentrate an aqueous protein solution, a method for producing the same, and a method for using the same. [Means for Solving the Problems] The hollow fiber membrane type separation membrane of the present invention is characterized in that in the separation membrane for protein and / or peptide analysis pretreatment, the separation coefficient of the separation membrane with respect to dextran having a weight average molecular weight of 10,000 is 0.4 or less. To do. [Selection figure] None |
