A cell separation device includes a channel or chamber in which a sample flows or moves, the sample including target cells marked with magnetic particles, and non-target cells, and a magnet which generates a magnetic first force in a first direction with respect to the sample within the channel or chamber. The channel or chamber of the cell separation device is applied with a second force in a second direction opposite to the first direction of the magnetic force. According to the cell separation device and a method of separating cells, the target cells move in the first direction by the magnetic force, and the non-target cells move in the second direction by the second force, by simultaneously applying the magnetic force and the second force in opposing directions, thereby separating the target cells from the non-target cells.

An ion exchangeable mixture containing a polymeric compound consisting of an ion exchange resin, an acrylamide mixture containing at least one bisacrylamide and at least one acrylamide, and a copolymer obtained by reacting the polymeric compound with the acrylamide mixture, and a method of producing the same are provided. The ion exchangeable membrane produced by using the ion exchangeable mixture has significantly smaller electric resistance than conventional ion exchangeable membranes, and has excellent selective permeability because the ion exchangeable membrane is electrically charged. The ion exchangeable membrane can be produced under very mild production conditions, and thus can be produced very easily. Furthermore, the ion exchangeable membrane can be also formed into film during a crosslinking reaction in a solvent of water, and thus is advantageous in that the ion exchangeable membrane can be freely produced into desired sizes, shapes and forms.
