Descriptions	Xylene Cyanol FF Xylene Cyanol FF MedChemExpress (MCE) HY-D0945 2650-17-1 97.46% 4°C, sealed storage, away from moisture and light In solvent : -80°C, 6 months Descriptions Xylene Cyanol FF Xylene Cyanol FF MedChemExpress (MCE) HY-D0945 2650-17-1 97.46% 4°C, sealed storage, away from moisture and light In solvent : -80°C, 6 months -20°C, 1 month (sealed storage, away from moisture and light) Room temperature in continental US may vary elsewhere. 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. Xylene Cyanol FF tracks DNA on different polyacrylamide gels. The operation is as follows[1]: 1. Used for denaturing gel. (1) Prepare gel: Contain 10% acrylamide (19:1, acrylamide:bisacrylamide), and 8.3 M urea. The operating condition is 55°C. (2) Prepare electrophoresis buffer: 89 mM Tris, HCl, pH 8.0, 89 mM boric acid, 2 mM EDTA (TBE). (3) Prepare loading buffer: 10 mM NaOH, 1 mM EDTA, and 0.1% Xylene Cyanol FF. (4) Gel is run at 70 W (50 V/cm, constant power) on an IBI model STS 45 electrophoresis unit, or 60 °C (31 V/cm, constant voltage) on a Hoefer SE 600 electrophoresis unit. (5) Dry the gel on Whatman 3MM paper and expose to X-ray film. Exposure time up to 15 hours. 2. Used for denaturing gel. (1) Prepare the gel: Contain 8% acrylamide (19:1, acrylamide:bisacrylamide). (2) Prepare DNA suspension: containing 40 mM TrisβHCl, pH 8.0, 20 mM acetic acid, 2 mM EDTA and 12.5 mM magnesium acetate (TAEMg). (3) Boil the DNA suspension and cool slowly to 16 °C. (4) Prepare staining solution: containing TAEMg, 50% glycerol, 0.02% bromophenol blue and 0.02% Xylene Cyanol FF. Bring up the sample to a final volume of 10 µL with this staining solution. (5) The gel is run on a Hoefer SE-600 gel electrophoresis unit at 11 V/cm at 16 °C and exposed to X-ray film for up to 15 hours or stained with Stainsall (HY-D0987). \| \| \| \| \| \| \| \| \| \| [1].
