Cat. No.: HY-D0023
CAS No.: 6358-69-6
Synonyms: HPTS; Solvent Green 7
Pyranine (HPTS; Solvent Green 7) is a cell-impermeant pH-sensitive fluorescent indicator. Pyranine acts as a class of fluorescent chemosensor for the Cu + ion. Pyranine is used as a coloring agent, biological stain, optical detecting reagent, and pH indicator (Ex/Em = 450/510 nm) .

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 .

18:1 PE CF (1,2-dioleoyl-sn-glycero-3-phosphoethanolamine-N-(carboxyfluorescein) (ammonium)) is a pH-sensitive fluorescent indicator. 18:1 PE CF exhibits changes in fluorescence intensity in response to pH variations and reflects the electrostatic states of cationic liposomes and lipoplexes. 18:1 PE CF supports real-time visualization of pH distribution and membrane deformation in giant unilamellar vesicles and is suitable for steady-state fluorescence testing in large unilamellar vesicle membranes. 18:1 PE CF is capable of monitoring the surface electrical potential of cationic liposomes and lipoplexes and can effectively label lipid bilayers and nanomicelles. 18:1 PE CF can be used for the research of the investigation of lung cancer (Ex = 495 nm; Em = 520 nm) .
