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.
