YO-PRO 1 Chemical Properties,Usage,Production

Description

YO-TAP-1 (Oxazole Yellow Monomer, also known as YO-PRO^®-1) is a green fluorescent carbocyanine monomeric dye. YO-TAP-1 is a cell-impermeant nucleic acid stain that is nonfluorescent in the absence of nucleic acids but exhibits a significant fluorescence enhancement upon binding to dsDNA.

YO-TAP-1 has a bright fluorescence signal and low background. The dye is useful for staining nucleic acids on microarrays, as well as for nuclear and chromosome counterstaining in microscopy. It may be used for monitoring of cell viability and apoptotic and dead cell detection in culture.

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.
