Xylene cyanole FF ≥75% (dye content), Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY

Xylene cyanol is often used as a tracking dye during agarose or polyacrylamide gel electrophoresis. It has a slightly negative charge and will migrate in the same direction as DNA, allowing the user to monitor the progress of molecules moving through the gel. The tracking dye typically migrates with the DNA molecules around 5 kb. Xylene cyanol may also be used in loading buffer that facilitates the observation of the sample during gel loading and electrophoresis.

Naphthalene black 10B (naphthol blue black, acid black 1) 80% (dye content), Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY

Naphthol blue black (NBB) is an textile diazo dye, with high photo- and thermal-stability. Photoelectrochemical degradation of this dye yields colorless quinone as end product. Pure grade of NBB is generally used for dyeing foodstuffs, drugs and cosmetics. It is also used as a protein stain in chromatography and electrophoresis and as a biological stain. Commercial grade of NBB is a widely used textile dye. It is used in dyeing wool, nylon, silk and in textile printing. In addition, it is also employed for colouring of soaps, anodised aluminum and casein, wood stains and writing ink preparation.
