Supplier: Thermo Scientific Chemicals
Description: 6-Carboxyfluorescein 96%

Catalog Number: (89139-250)
Supplier: Biotium
Description: 5(6)-CFDA (full name: 5-(and-6)-Carboxyfluorescein diacetate) is membrane-permeant and thus can be loaded into cells via incubation.


Supplier: AAT BIOQUEST INC
Description: 6-FAM is the other purified isomer of 5(6)-carboxyfluorescein.

Catalog Number: (89139-260)
Supplier: Biotium
Description: 5-Carboxyfluorescein has a pKa of 6.5 and can be used as a pH sensor. The excitation spectrum of the dye responds to pH similarly to that of BCECF. Carboxyfluorescein can also be used as a tracer dye. The dye is membrane-impermeant and can be loaded into cells by microinjection or scrape loading.


Catalog Number: (89139-556)
Supplier: Biotium
Description: 6-FAM, SE (full name: 6-Carboxyfluorescein, succinimidyl ester, single isomer) is the amine-reactive form of 6-carboxyfluorescein single isomer.
6-FAM SE is an amine-reactive green fluorescent dye widely used for labeling oligonucleotides or other biomolecules that contain a primary or secondary aliphatic amine. The coupling reaction is usually carried out at pH 8-9.5.


Supplier: Thermo Scientific Chemicals
Description: 4(5)-Carboxyfluorescein. Grade: 99. Melting Point Cca 300*. Boiling Point C: NA. C21H12O7. 72088-94-9.
Supplier: Adipogen
Description: The amine-reactive fluorescein derivatives are probably the most common fluorescent derivatization reagents for covalently labeling proteins. Carboxyfluorescein is better retained in cells than is fluorescein, its pKa of ~6.5 is lower than the cytosolic pH of most cells (pH ~6.8-7.4). Carboxyfluorescein is commonly employed as a polar tracer.

Supplier: AAT BIOQUEST INC
Description: 5-FAM is the purified single isomer of carboxyfluorescein.

Supplier: Adipogen
Description: CFDA is a popular, sensitive, fluorescent substrate for measuring esterase activity in live cells. It is often used in cell viability assays and "Live-Dead" assay systems, especially automated cell viability assays. The cleavage product produced upon enzymatic or chemical hydrolysis of the acetate group(s) is carboxyfluorescein which is well-retained inside live cells, while the substrate CFDA is membrane permeant.

Supplier: Anaspec Inc
Description: 6-FAM is another isomer of carboxyfluorescein. It is mainly used in sequencing of nucleic acids and labeling nucleotides.

Supplier: TCI America
Description: 5-Carboxyfluorescein Diacetate, CAS Number: 79955-27-4, Purity: 93.0% Pure, Molecular Formula: C25H16O9, Molecular Weight: 460.39 g/mol, Synonyms: 5-CFD, Physical Form: Solid, Size: 50MG

Catalog Number: (89139-262)
Supplier: Biotium
Description: 6-Carboxyfluorescein has a pKa of 6.5 and can be used as a pH sensor. The excitation spectrum of the dye responds to pH similarly to that of BCECF. Carboxyfluorescein can also be used as a tracer dye. The dye is membrane-impermeant and can be loaded into cells by microinjection or scrape loading.


Supplier: Ambeed
Description: 6-Carboxyfluorescein 98%

Supplier: Thermo Scientific Chemicals
Description: 5-Carboxyfluorescein 95%

Supplier: Adipogen
Description: Carboxyfluorescein is commonly employed as a polar tracer and used for intracellular pH measurements. It has also been used for studying viability of various types of bacteria.

Supplier: AAT BIOQUEST INC
Description: Carboxyfluorescein (commonly called FAM) and its amine-reactive succinimidyl esters are favored over FITC in bioconjugations.
