概要

DNA Loading Dye is a ready-to-use marker dye containing orange G (0.4%), bromophenol blue (0.03%), and xylene cyanol FF (0.03%), in 15% Ficoll® 400, 10 mM Tris-HCl (pH 7.5), and 50 mM EDTA (pH 8.0). The dye is used for loading DNA samples into agarose gel wells and tracking migration during electrophoresis. In a 0.5 - 1.4% agarose gel in 0.5X TBE, xylene cyanol FF migrates at approximately 4 kb, bromophenol blue at approximately 300 bp, and orange G at approximately 50 bp. This product is free of nuclease activity.
