Description

<p>A two-dimensional electrophoresis method, involving involves isoelectric focusing in the first dimension and polyacrylamide gel electrophoresis in the second dimension, is commonly used for the separation and analysis of protein mixtures. However, conventional methods have some drawbacks such as complex experimental procedures, long analysis time, and high consumption of reagents. In this study, based on the knowledge gained from our previous research on digital electrophoresis, a cartridge device with heterogeneous functionalized gels arranged and integrated in a two-dimensional pattern was used. The fundamental evaluation using model proteins confirmed the feasibility of sample introduction using the developed devices, digital sieving electrophoresis, and digital isoelectric focusing using pH-buffered gels. Furthermore, the verification of two-dimensional digital electrophoresis using a cartridge device with multiple pH-buffered gels and molecular sieving gels demonstrated continuous two-dimensional digital separation by employing the single device.</p>
