DAPI is a commonly used nuclear counterstain for fixed cells that emits blue fluorescence when bound to DNA. With NucBlue® Fixed Cell ReadyProbes® Reagent, we have formulated a high-purity form of this classic stain in a room temperature-stable solution that is provided in a convenient-to-use dropper bottle. It has the following features:
• No need to dilute, weigh, or pipette
• Convenient dropper bottle—just use two drops per mL
• Stable at room temperature—keep handy at your scope or cell culture area• DAPI is excited with UV light and detected through a blue/cyan filter
