AUTOMATIC STAINING METHOD AND STAINING DEVICE FOR BIOPOLYMER

摘要

An automatic staining method and staining device for a biopolymer. The method comprises: combining stains with biopolymers to be stained, separating the uncombined stain from the biopolymers already combined with the stains; and the whole staining process is performed in one container, wherein the separation of the uncombined stains from the biopolymers combined with the stain comprises: removing the remaining stain first, adding a destaining solution, and placing the destaining solution, the residual stain and the stained biopolymers in a medium to which an electric field is imposed, so as to enable the stains not combined with the biopolymers to be completely removed or partly removed from the medium and the biopolymers to remain in the medium. The method does not require the consumption of disposable thickened filter paper, thereby saving costs. In addition, the method and device utilize an electric field to accelerate charged biopolymer stains, which enables the charged biopolymer to quickly combine with biopolymers, and can enable the uncombined stains to be quickly separated from biopolymers combined with the stains, thereby shortening the entire staining time period and saving costs. The operation is simple, and staining and destaining can be automatically completed in an instrument.
