PURPOSE:To obtain a polyacrylamide gel film-based electrophoretic medium material using a resin film as the support with the resolutions equal to the electrophoretic medium material produced using a glass plate as the support, by providing an oxygen transmission preventing layer made of an oxide or a sulfide of a specified metal element between a medium layer for electrophoresis and a support layer. CONSTITUTION:A medium material for electrophoresis which includes an electrophoretic medium layer made of a polyacrylamide based water gel and containing a compound having at least one carbamoyl group as the modifying agent, and a resin support is provided with an oxygen transmission preventing layer made of an oxide or a sulfide of a metal element as selected from a group of V, Cr, Ni, Cu, Ga, In, G and Sn between the medium layer for electrophoresis and the support layer. The oxygen transmission of a laminate body comprising the oxygen transmission preventing layer and the support body is preferably below 10cc/m<2>.atm per day. |
