Xylene Cyanole FF

Catalog Number: HS-608
Size: 25 g

Xylene Cyanole is a tracking dye for DNA electrophoresis.

Coomassie Blue G – 250 is a useful stain for protein detection in PAGE gels. Coomassie staining gives blue bands on a clear background, with a sensitivity of 100 – 500 ng/band. The G – 250 dye is converted to a leuco form below pH 2-3. The leuco form regains color on protein binding, and is the basis for the Bradford Protein Assay.

Bromophenol Blue

Catalog Number: HS-603
Size: 10 g

Bromophenol Blue is used as a tracking dye, because its charge/mass ratio allows it to comigrate with smaller macromolecules through PAGE and Agarose gels. The dye undergoes a color shift to yellow at acidic pH.
