Cat. No.: HY-D0077
CAS No.: 195136-58-4
Synonyms: Oregon green 488
Target:  

Fluorescent Dye

Research Areas:

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 .

Cancer

Ala-parafluoroPhe-Arg-Cha-Cit-Tyr-NH2 TFA, a bioactive peptide, is a selective Protease activating receptor 1 (PAR-1) agonist over PAR-2. PAR-1 belongs to a subfamily of G-protein coupled receptors and is known to mediate the cellular effects of thrombin. In addition to its varied cellular effects of thrombin, PAR-1 has also been shown to coordinate with PAR-4 and regulate thrombin-induced hepatocellular carcinoma harboring thrombin formation within the tumor environment classified as 'coagulation type' .

Others

Ser-parafluoroPhe-Aad-Leu-Arg-Asn-Pro-NH2 is a biological active peptide. (Structure-activity studies of thrombin receptor-tethered ligand SFLLRNP have revealed the importance of the Phe-2-phenyl group in receptor recognition and the replacement of the Phe-2 by para-fluorophenylalanine [(p-F)Phe] was found to enhance its activity)
