Bromophenol blue

溴酚藍(lán)

C₁₉H₁₀Br₄O₅S      MW  669.97      CAS：115-39-9 

Storage：RT

Appearance………..orange to tan power

說明：Bromophenol blue is often used as a color marker to monitor the process of agarose gel electrophoresis and polyacrylamide gel electrophoresis. Since bromophenol blue carries a slight negative charge at moderate pH, it will migrate in the same direction as DNA or protein in a gel; the rate at which it migrates varies according to gel density and buffer composition, but in a typical 1% agarose gel in TAE buffer or TBE buffer, bromophenol blue migrates at the same rate as a DNA fragment of approximately 500 base pairs.
