This paper introduced the simple and rapid methods of silver staining and gel preservation. It was taken only about 10 and 15 minutes to stain a gel. The background of gel was light, the bands were clear, the sensibility was high and the stabilization was well by the method of silver staining. The gel preservation adopted a method named two-layer transparent plastic paper "Sandwich" which could keep the gel with primitive colors for a long time. The methods were used on PAG checking and SSCP typing of HLA and the results were satisfactory. The set of methods are expected to be widely used in laboratories.
