λ DNA digested with Lsp1109I (BbvI), 1.4% agarose, 199 cleavage sites

Regular restriction endonucleases are large collections of high quality restriction enzymes optimized to function in one buffer of a five-buffer system. In addition, a universal Tango buffer is provided to facilitate double enzyme digestion. All enzymes demonstrated 100% activity under recommended buffers and reaction conditions. To ensure consistent performance, Thermo Scientific Restriction Enzyme Reaction Buffers contain premixed BSA, which enhances the stability of multiple enzymes and binds contaminants that may be present in DNA preparations.
