一种跟踪染料，用于琼脂糖核酸电泳或DNA测序的聚丙烯酰胺凝胶电泳。 推进0.05%的浓度，2% 储备液可配成 5-10× buffer. Xylene cyanol is often used as a tracking dye during agarose or polyacrylamide gel electrophoresis. It has a slight negative charge and will migrate the same direction as DNA, allowing the user to monitor the progress of molecules moving through the gel. The rate of migration varies with gel composition. Xylene Cyanol FF is used as a: · histological stain and as tracker dye in DNA sequencing and electrophoresis · gel-loading dye · formamide RNA loading dye · tracking dye in native polyacrylamide gel electrophoresis (PAGE) loading buffer
