    2',7'-Difluorofluorescein

    Oregon green 488

    		 Fluorescent Dye Others
    2',7'-Difluorofluorescein (Oregon green 488) is a fluorescein derivative and a pH-sensitive fluorescent probe (pKa ~4.7). Upon excitation at 488 nm, 2',7'-Difluorofluorescein exhibits pH-sensitive fluorescence intensity through the formation of dianions, while its pH sensitivity decreases under excitation at 450 nm, allowing its use in ratiometric pH analysis. 2',7'-Difluorofluorescein can be used for the quantitative analysis of pH values in the range of 2-7 in submicron aerosol particles. 2',7'-Difluorofluorescein undergoes buffer-mediated and buffer-free excited-state proton transfer between different protonated forms, and its cationic form undergoes rapid excited-state deprotonation. 2',7'-Difluorofluorescein is resistant to photodegradation, maintains stable absorption and fluorescence properties within the physiological pH range, and serves as a fluorescent protein label, a component of Ca 2+ indicators, a fluorescent imaging agent, and an anisotropy probe .

    U-104067

    		Fluorescent Dye Others
    U-104067 can be used as a molecular probe to observe and to quantitate a variety of physical phenomena, such as transfer into lipid membranes, partitioning between surface phases, and partitioning between lipid carriers and target membranes. U-104067 is a sensitive reporter of the tilt/ripple phase transition, monitored by its fluorescence anisotropy and quantum yield changes .

    BODi-1

    		DNA Stain Others
    BODi-1 is a fluorescent modulator targeting dsDNA, which binds to dsDNA via a bis-intercalation mechanism (Ex=465 nm, Em=490 nm). BODi-1 exhibits a fluorescence enhancement effect upon binding to nucleic acids, but its fluorescence intensity, anisotropy and average lifetime decrease at higher dye/DNA ratios. When BODi-1 binds to DNA in liposome complexes, it also shows red-shifted emission spectra, along with reduced quantum yield and average lifetime. BODi-1 does not induce significant DNA conformational changes when the dye/DNA ratio is below 0.01. BODi-1 can be used as a fluorescent probe for the characterization of liposome complexes and FRET studies at this ratio .
