Uniblue A

Uniblue A is a derivative of the textile dye Remazol Brilliant Blue R, which is frequently applied to wool. Uniblue A, however, a relatively common synthetic dye, is often utilized as a protein stain for electrophoresis. Introduced for analytical purposes by Swedish scientist Arne Tiselius around 1930, electrophoresis is the movement of charged particles or molecules through a fluid when exposed to an electric field, which is typically supplied by electrodes submerged in the solution. Electrophoresis can be used to analyze molecular structure as well as to break apart various substances, especially proteins.
