Fluorescein derivative with amine group, contains pure 6-isomer of the fluorophore. This reagent can be used for the modification of biomolecules by enzymatic transamination. Its aliphatic amine groups also reacts with electrophiles (like activated esters). This amine can be also conjugated with carbonyl compounds (aldehydes and ketones) by means of reductive amination.

FAM azide, 6-isomer

FAM (fluorescein) azide, 6-isomer is a commonly used fluorescent dye azide for Click Chemistry.

Coumarin 343 X azide

Coumarin 343 is a blue emitting fluorophore that can serve as a FRET donor for fluorescein (FAM). This azide derivative can be conjugated with alkynes by Click chemistry. An extended linker arm between the fluorophore and the azide group enhances solubility, and provides spatial separation between the dye and the biomolecule.

Sulfo-Cyanine5.5 maleimide

Sulfo-Cyanine5.5 is a water-soluble far red emitting dye. This is a thiol reactive maleimide derivative of sulfo-Cyanine5.5. It is recommended for the labeling of sensitive proteins.
