A simple apparatus for gel staining used in two-dimensional electrophoresis

Two-dimensional electrophoresis was widely used in molecular biology. It was required that all gels be in the same condition. The gels can be controlled in the same condition easily during SDS-PAGE. But no paper reported how to ensure the gels were in the same condition during being stained. When the common protein gel staining plates were used, keeping the gels in the same treatment was impossible. A new apparatus was designed in this paper. The apparatus can ensure all of the gels in the same condition during being stained. Furthermore, the problems such as gels being broken, being covered by others can also be prevented when the new apparatus was used.
