DAPI (4,6-Diamidino-2-phenylindole dihydrochloride) CAS:28718-90-3

DAPI (4,6-Diamidino-2-phenylindole dihydrochloride) is a fluorescent dye commonly used in biological research for visualizing DNA. It binds to the minor groove of double-stranded DNA and emits blue fluorescence when illuminated with ultraviolet light. DAPI is often used in fluorescence microscopy to stain cell nuclei, making it a valuable tool for studying the structure and organization of DNA within cells. It is also used in flow cytometry to analyze DNA content in individual cells and in other techniques for DNA visualization and quantification. DAPI's high affinity for DNA and its specific fluorescent properties make it a versatile and widely used tool in molecular and cell biology research.
