产品说明

一般描述

Xylene cyanol is often used as a tracking dye during agarose or polyacrylamide gel electrophoresis. It has a slightly negative charge and will migrate in the same direction as DNA, allowing the user to monitor the progress of molecules moving through the gel. The tracking dye typically migrates with the DNA molecules around 5kb. Xylene cyanol may also be used in loading buffer that facilitates the observation of the sample during gel loading and electrophoresis.
