| Bioactivity | Xylene Cyanol FF is an acid triphenylmethane dye. Xylene Cyanol FF can be used for histochemical staining of hemoglobin peroxidase or as a tracking dye for DNA sequencing in electrophoresis. Xylene Cyanol FF will be catalyzed by Fe and Al to accelerate oxidation under the addition of double oxidant hydrogen peroxide and potassium periodate. Xylene Cyanol FF thus enables the spectrophotometric determination of Fe and Al in the solution to be tested[1][2]. |
