    摘要: The present invention aims to provide a porous separation membrane that does not suffer a significant decrease in the protein permeability even after long term use. The porous separation membrane has an asymmetric structure with a dense layer forming one surface layer and with a coarse layer forming the other surface layer, supports a biocompatible polymer, and meet the requirements (1) and (2) given below in surface analysis of a cross section containing the dense layer and the coarse layer performed by TOF-SIMS:
    (1) the minimum value of normalized intensity of the ion signal attributed to the biocompatible polymer in the coarse layer is 0.15 times or more of the maximum value, and
    (2) the normalized average intensity of the ion signal attributed to the biocompatible polymer in the dense layer is 2.0 times or more of the normalized average intensity of the ion signal attributed to carboxylic acid in the coarse layer.

    (A) the porous fiber has a non-hollow shape,
    (B) an arithmetic average roughness (dry Ra value) of a surface of the porous fiber in a dry state is 11 nm or more and 30 nm or less,
    (C) an arithmetic average roughness (wet Ra value) of a surface of the porous fiber in a wet state is 12 nm or more and 40 nm or less,
    (D) a value represented by wet Ra/dry Ra is 1.05 or more, and
    (E) a linear rate of the fiber bundle represented by (length of fiber bundle)/(length of one porous fiber) is 0.97 or more and 1.00 or less.

    摘要: An object of the present invention is to provide a hollow fiber membrane module which makes it possible to concentrate incubated platelets by efficiently removing water from an incubated platelet suspension liquid containing incubated platelets while suppressing deterioration of the function of the incubated platelets. The present invention provides an incubated platelet concentration module in which a plurality of hollow fiber membranes each having pores with an average pore diameter of 2 µm or less on a surface of the hollow fiber membrane are packed in a casing having at least one inlet for supplying an incubated platelet suspension liquid before concentration into the hollow fiber membranes, wherein a value (X/Y1) obtained by dividing a total cross-sectional area (X) of the plurality of hollow fiber membranes by a total cross-sectional area (Y1) of the least one inlet is 4.0 or less.
