摘要： 本文介绍了一套简单快速的DNA银染以及胶保存的方法，整个过程仅需10~15分钟，而且背景浅，条带清楚，灵敏度高，稳定性好。胶保存采用双层玻璃纸夹心法，可长久地保存胶显色时的原貌。以常规PAG胶检测和HLA的SSCP分型为例，利用该套方法进行了银染以及胶的保存，均得到了满意的结果。该方法具有推广价值。
Abstract: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.
