Oxazole Yellow iodide is also known as Yo-Pro-1 or YP1. It is a carbocyanine nucleic acid stain which has a strong binding affinity to nucleic acids.
It is a green fluorescent DNA marker which is commonly used to identify apoptotic cells.
Uses and applications
Oxazole Yellow (YP1) does not penetrate the plasma membrane of viable cells. However, during apoptosis, apoptotic processes cause the cell-membrane to become slightly permeable. This allows Oxazole Yellow (YP1) to enter these cells and bind to nucleic acids to allow detection of apoptotic cells.
It is frequently used with propidium iodide when staining for apoptotic and necrotic cells as apoptotic cells remain impermeant to propidium iodide but permeable to Oxazole Yellow (YP1).
