Recommended Use
Bromophenol Blue is used as a tracking dye to monitor the progress of an electrophoresis
separation. Bromophenol Blue usually comigrates with DNA molecules around 0.5kb.
Therefore, Bromophenol Blue provides an index of the mobility of the fastest fragments and
is valuable in determining the length of the gel over which the separation of DNA has
occurred.
Please Note: Tracking dyes may interfere with the ability to visualize the fragments that
comigrate with them.
Storage
Store in the dark at room temperature, protected from moisture. Keep tightly sealed.
