The Bromophenol Blue Analytical Grade ACS by Dinâmica, available at LojaLab, is a sulfonephthalein dye used as an acid-base indicator and electrophoresis tracking dye. Its visual transition occurs approximately between pH 3.0 and 4.6, changing from yellow in more acidic media to blue or blue-violet under less acidic conditions. Migration speed depends on gel, buffer, voltage, concentration and sample composition.
