Abstract: A microfluidic system having a microchannel for the capillary transport of a liquid, in particular a body fluid for analytical purposes. The microchannel is provided with a surface coating comprising at least one hydrophilic substance selected from the group consisting of polyacrylic acid, polyacrylate, dextran sulfate and chondroitin sulfate. The invention also concerns a coating method that is suitable for this.

Abstract: A disposable electrophoresis device for separation of a complex protein sample, using two-dimensional gel electrophoresis and method thereof are disclosed. The device comprises a carrier with a first area for a first dimension gel strip and a second area for a second dimension gel, where the two areas are directly in contact with each other. The device further comprises a body made of a hard component and an elastic component layer at a variable distance from the carrier. The body further comprises at least one cavity for external actuation of at least one valve, wherein the valve is represented by the elastic component layer.
