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.

PolyFreeze is a water-soluble support matrix and a form of embedding medium for frozen sectioning. PolyFreeze sections flawlessly at routine frozen specimen thickness of 5-6 μ and leaves no slide residue. It provides for -20 ºC cryostat sectioning in rapid set embedment. This medium freezes quickly supporting the tissue for sectioning at 3 mm and up with no cracking of the matrix at temperatures from -8 °C to -25 °C.

ACCUSPIN System-Histopaque-1077 products are intended for use in the isolation of lymphocytes and other mononuclear cells. The separation medium, Histopaque-1077, is a sterile-filtered, endotoxin-tested solution of polysucrose and sodium diatrizoate, adjusted to a density of 1,077 g/ml. ACCUSPIN System-HISTOPAQUE-1077 employs γ-irradiated 50 mL polypropylene centrifuge tubes specially designed with two chambers separated by a porous high-density polyethylene barrier ('frit'). Each tube is aseptically filled with 15 ml of Histopaque 1077. Each tube will separate 15-30 mL of anticoagulated blood.
