Provided is a barrier film which is less likely to undergo deterioration of gas barrier properties even after the Gelbo Flex test. The barrier film according to the present invention includes a barrier coat layer, an inorganic oxide vapor deposition layer, and a substrate layer in this order, the barrier coat layer being a cured film of a barrier coat composition containing: a hydrolyzed product of an alkoxysilane represented by the following General Formula (I): Si(OR). . . (I), wherein Rrepresents an organic functional group; a water-soluble polymer; and a hydrolyzed product of a silane coupling agent represented by the following General Formula (II): RSi(OR). . . (II), wherein Rand Reach independently represent an organic functional group, and n is 2 or 3.

The present invention provides a method of purifying highly pure retinal pigment epithelial cells from a cell population obtained by induction of differentiation of pluripotent stem cells into retinal pigment epithelial cells, by a simple and easy operation in a short period. The purification method of the present invention includes a step of introducing a cell population containing retinal pigment epithelial cells obtained by differentiation induction of pluripotent stem cells on laminin or a fragment thereof on a filter, and obtaining a cell population that passed the filter.

Method for purification of retinal pigment epithelial cells

The present invention is to provide a metal particle dispersion which has low viscosity and excellent dispersibility and dispersion stability, and in which the precipitation of the metal particles is inhibited. Disclosed is a metal particle dispersion comprising metal particles, a dispersant and a solvent, wherein the metal particles contain one or more selected from the group consisting of gold, silver, copper, nickel, platinum, palladium, molybdenum, aluminum, antimony, tin, chromium, lanthanum, indium, gallium and germanium, and wherein the dispersant is a graft copolymer having at least one constitutional unit represented by the following general formula (I) and at least one constitutional unit represented by the following general formula (II), and in which at least part of nitrogen sites of the constitutional units represented by the general formula (I) each form a salt with at least one selected from the group consisting of a halogenated hydrocarbon, an acidic phosphorus compound represented by the following general formula (V), and a sulfonic acid compound represented by the following general formula (VI): (symbols shown in the general formulae (I), (II), (V) and (VI) are as described in the Description.)
