6fam

6-Carboxyfluorescein (6-FAM) contains a carboxylic acid functional group, facilitating reactions with primary amines through carbodiimide activation.

6-FAM SE (6-Carboxyfluorescein N-succinimidyl ester) is another isomer of carboxyfluorescein. 6-FAM SE is mainly used for labeling nucleotides and sequencing nucleic acids.

FAM azide, 6-isomer (6-FAM azide), is a fluorescent dye and a click chemistry reagent characterized by its azide moiety. The azide group enables copper-catalyzed azide-alkyne cycloaddition reactions (CuAAc) with molecules containing alkyne groups. Additionally, it can undergo strain-promoted azide-alkyne cycloaddition (SPAAC) with molecules that have DBCO or BCN groups.

6-FAM-PEG3-Azide is a fluorescent dye for labeling oligonucleotides, whose azide group undergoes click chemistry reactions with molecules containing alkyne, DBCO, or BCN groups.

5'6-FAM-UUCUCCGAACGUGUCACGUTT, ACGUGACACGUUCGGAGAATT is a fluorescein (FAM)-labeled oligonucleotide, identified by the specified sequence.

5'6-FAM-GGUGAAAGACGAUGGACAATT,UUGUCCAUCGUCUUUCACCTT is a double-stranded ribonucleoside modified with the fluorescent molecule 5'6-FAM, a combination of 5-FAM and 6-FAM, exhibiting excitation/emission wavelengths at 490 nm/520 nm [1].
