Beschreibung: 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.

Beschreibung: Folin & Ciocalteu's phenol reagent is most commonly used in the Lowry method for determining protein concentration. It has also been used for the quantification of total phenolics. In this method, protein is pretreated with copper(II) in a modified biuret reagent (alkaline copper solution
stabilized with sodium potassium tartrate). Addition of the phenol reagent generates chromogens that give increasing absorbance between 550-750nm. Normally, absorbance at the peak (750 nm) or shoulder (660 nm) are used to quantitate protein concentrations between 1 - 100 mg/ml while absorbance at 550 nm is used to quantitate higher protein concentrations.

Beschreibung: Bis(cyclohexanone)oxaldihydrazone (Cuprizone) has been used in mice to study the effect of NG2 (neural/glial antigen 2) proteoglycan on toxic-induced demyelination. It has been used to induce demyelination in mice. It has been used to study cuprizone-induced demyelination and remyelination in the corpus callosum of mice.

Beschreibung: 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.
