6fam

6-FAM-PEG3-Azide is a fluorescent dye and click chemistry reagent utilized for labeling oligonucleotides [1]. It features an azide group that participates in copper-catalyzed azide-alkyne cycloaddition (CuAAc) with alkyne-bearing molecules. Furthermore, it is capable of engaging in strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules containing DBCO or BCN groups.

FAM hydrazide, 6-isomer, a fluorescein (FAM) derivative belonging to the xanthene dye family, serves as a labeling agent for carbonyl compounds, including aldehydes and ketones [1].

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.

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

5(6)-FAM SE (5(6)-Carboxyfluorescein N-hydroxysuccinimide ester) is an amine-reactive green fluorescent dye. 5(6)-FAM SE is widely used for labeling proteins or other molecules that contain a primary or secondary aliphatic amine.
