Oxazole Yellow (YO-PRO®-1), 1 mM in DMSO
Oxazole Yellow, also known as YO-PRO®-1, is a green-fluorescent, cell-impermeant nucleic acid stain that can be used as a early marker of apoptosis.
Oxazole Yellow, also known as YO-PRO®-1, is a green-fluorescent, cell-impermeant, high-affinity carbocyanine monomeric nucleic acid stain. It is essentially non-fluorescent in the absence of nucleic acids but exhibits excitation/emission maxima 491/506 nm when bound to nucleic acids. Oxazole Yellow is also used to identify apoptotic cells. Early apoptotic cells become permeant to Oxazole Yellow, but remain impermeant to propidium iodide (cat. no. 40016), a dead cell stain.
- Monomeric nucleic acid stain
- Early marker of apoptosis
- λEx/λEm (with DNA) = 491/506 nm
- Supplied at 1 mM in DMSO
- MW: 629
