Descripción general

Xylenol Orange tetrasodium salt is a fluorochrome acid dye with complexing and chelating properties that make it useful as an indicator in the spectrophotometric detection and assay of metal ions such as calcium, cadmium, bismuth, zinc, lead, and mercury. Its tetrasodium salt especially is used as an indicator in metal titrations. It changes color from yellow to red between pH 6.4 to 10.4. It has six potentially anionic substituents, one being sulfonate, and is anionic under staining conditions and during most laboratory applications.
Application
Xylenol Orange has been used as a vital stain to study calcification in bone development, injury, and repair.
It has been used in the fluorescent histochemical detection of alkaline phosphatase.
It has been used in FBX (ferrous benzoic xylenol orange) gel preparation to study the effects of MRI (magnetic resonance imaging) parameters on image quality.

Nota

Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
