Agarose gel electrophoresis is a method of gel electrophoresis used in biochemistry, molecular biology, genetics, and clinical chemistry to separate a mixed population of macromolecules such as DNA or proteins in a matrix of agarose, one of the two main components of agar.
Bromophenol blue (3′,3″,5′,5″-tetrabromophenolsulfonphthalein, BPB, albutest) is used as a pH indicator, a color marker, and a dye.
A color marker is used to monitor the progress of agarose gel electrophoresis and polyacrylamide gel electrophoresis (PAGE) since DNA, RNA, and most proteins are colourless.
A dye is a colored substance that has an affinity to the substrate to which it is being applied.
Orange G or orange gelb is a synthetic azo dye used in histology in many staining formulations.
Polyacrylamide gel electrophoresis (PAGE) is a technique widely used in biochemistry, forensic chemistry, genetics, molecular biology and biotechnology to separate biological macromolecules, usually proteins or nucleic acids, according to their electrophoretic mobility.
