  • Cresol Red is a very convenient dye. At a concentration of about 0.2mM it is compatible with restriction digestion, PCR, sequencing. It may be used as marker for electrophoresis.
  • the color of the dye is pH-dependent (red, if pH>7.5; yellow, if pH <7.5). It is possible to use Cresol Red as pH-indicator (i) for denaturation of double-stranded DNA in sequencing, (ii) for silica-purification of DNA from agarose gel.
