YO-PRO 1 Chemical Properties,Usage,Production

Definition

ChEBI: An unsymmetrical C1 cyanine dye having 1,3-benzoxazol-2-yl and quinolinium-4-yl substituents.

Biochem/physiol Actions

Oxazole yellow is a fluorescent cyanine dye that binds to DNA and is used to detect apoptotic cells. Oxazole yellow does not enter live cells. However, during apoptosis the cytoplasmic membrane becomes slightly permeable, allowing entry of the dye. Oxazole yellow is often used along with propidium iodide (catalog no. P4170), a DNA dead cell stain that does not enter either live or apoptotic cells. The λEx/λEm of Oxazole yellow is 491/509.

storage

-20°C (protect from light)
