The present invention concerns a method for the in vitro detection of an increased risk of diabetic nephropathy in a subject suffering from diabetes and being normoalbuminuric. Another aspect of the invention pertains to a method for the in vitro identification of a marker for prediction of diabetic nephropathy. Finally, the invention concerns a kit comprising means for detecting at least two proteins selected from the group consisting of heparan sulfate proteoglycan core protein or fragments thereof, carbonic anhydrase 1, prothrombin or fragments thereof, tetranectin, CD59 glycoprotein, plasma serine protease inhibitor, mannan-binding lectin serine protease 2 or isoforms thereof, antithrombin-III, alpha-1-antitrypsin, collagen alpha-1(I) chain, alpha-enolase, histone H2B type 1-O, glutaminyl-peptide cyclotransferase, protein AMBP and zinc-alpha-2-glycoprotein.

A system for outputting electropherograms includes a capillary containing a separation medium and comprising an inlet end, a distal end, and an interrogation region between the inlet and distal ends, the inlet end of the capillary configured to receive a plurality of differing samples containing DNA fragments having a plurality of different sizes; a power source configured to selectively apply forward and reverse polarity voltages between the inlet end and the distal end of the capillary; a detector configured to detect signal associated with DNA fragments moving through the interrogation region of the capillary; and a processor communicatively coupled to the detector and configured to process signal detected by the detector and output electropherograms during an electrophoresis run, the electropherograms corresponding to a plurality of differing samples successively introduced to the capillary from the inlet and traveling through the capillary at the same time.

A frame member-equipped transfer film (10) is provided with a transfer film (1) to which a sample separated by electrophoresis is transferred, and a pair of frames (2) that individually support two sides of the transfer film (1), namely a first side of the transfer film (1) and a second side opposite the first side.

Provided herein is an apparatus for gel electrophoresis comprising a cassette and a comb having at least one wedge-shaped tooth.
