Introduction

Ready Gel TBE gels are ideal for separating small dsDNA fragments, especially PCR products. The uniform
nature of DNA molecules provides samples with near-uniform charge to mass ratio, allowing nondenaturing
nucleic acid PAGE to separate dsDNA by mass using a continuous TBE buffer system.
