ELECTROPHORETIC MOBILITY-SHIFT Kit，E33075，Invitrogen

This fluorescence-based Electrophoretic Mobility Shift Assay (EMSA) Kit provides a fast, easy and quantitative method to detect both nucleic acid and protein in the same gel. This kit uses two fluorescent dyes for detection - SYBR® Green EMSA nucleic acid gel stain for RNA or DNA detection and SYPRO® Ruby EMSA protein gel stain for protein detection. The nucleic acids and proteins are stained sequentially in the gel after electrophoresis, so there is no possibility that labeling will interfere with the protein binding being assayed. Staining only takes about 20 minutes for nucleic acid, and then about 4 hours for the subsequent protein staining.
