Dyes With an Amine Group
CF® Dye Amines can be used to conjugate CF® dyes to carboxylic acids groups in biological molecules. Carboxylic acids can be activated using water soluble carbodiimides like EDC (EDAC) to react with amine-functionalized dyes to form a stable amide bond.
Dyes or biotin with amine groups like Lucifer Yellow Cadaverine or Neurobiotin™ are also used as fluid phase markers for neuronal tracing, as well as gap junction studies.

CF® Dyes with a reactive amine group to fluorescently label carboxylic acid groups in proteins and other molecules.
2-Sulforhodamine 101 Cadaverine, Trifluoroacetate Salt
2-Sulforhodamine 101 cadaverine can be coupled to activated carboxy groups or sulfonyl chlorides.
4-Sulforhodamine 101 Cadaverine, Trifluoroacetate Salt
4-Sulforhodamine 101 cadaverine can be coupled to activated carboxy groups or sulfonyl chlorides.
6-TAMRA Cadaverine, Trifluoroacetate Salt
6-Tetramethylrhodamine (TAMRA) cadaverine can be coupled to activated carboxy groups or sulfonyl chlorides.
ANTS
ANTS (8-aminonaphthalene-1,3,6-trisulfonic acid, disodium salt) is a highly negatively charged dye with an amino group that can be coupled to an aldehyde or ketone group to form an unstable Schiff base. The Schiff base is usually chemically reduced by sodium borohydride (NaBH4) or sodium cyanoborohydride (NaB(CN)H3) to form a stable linkage (1).
Biotin Ethylenediamine, Hydrochloride
Biotin ethylenediamine, hydrochloride is functionally equivalent to Neurobiotin™ (biotin ethylenediamine, hydrobromide, 90057).
Carboxyrhodamine 110-PEO3-amine, TFA salt, 5 isomer
5-CR110-PEO3-amine has a long water-soluble PEG spacer that separates the green fluorescent CR110 and the amine functional group.
Fluorescein cadaverine
Fluorescein cadaverine can be coupled to activated carboxy groups or sulfonyl chlorides.
Fluorescein Hexylamine
Fluorescein hexylamine can be coupled to activated carboxy groups or sulfonyl chlorides. This product could be used as a direct replacement to fluorescein cadaverine (cat#: 92000).
Lucifer Yellow Cadaverine
Like Lucifer Yellow CH, Lucifer Yellow Cadaverine can be used as a fixable fluorescent tracer. In addition, the dye can be used to conjugate to carboxylic acid groups.
NBD-Ethylenediamine
The fluorescence of NBD is highly dependent on the environment; it is virtually nonfluorescent in water but becomes strongly green fluorescent in hydrophobic media. NBD-ethylenediamine can be readily coupled to activated carboxy groups or sulfonyl chlorides.
ROX Cadaverine, Trifluoroacetate Salt
90108, 91060, - 90121View allHide
ROX cadaverine can be coupled to activated carboxy groups or sulfonyl chlorides.
Sulforhodamine 101 (Texas Red®) Cadaverine
Sulforhodamine 101 cadaverine can be coupled to activated carboxy groups or sulfonyl chlorides.
Sulforhodamine 101 (Texas Red®)-PEO3-Amine
Sulforhodamine 101-PEO3-amine has a long water-soluble spacer separating the dye and the amine group. The dye can be coupled to activated carboxy groups or sulfonyl chlorides.
TAMRA cadaverine (mixed isomers)
Tetramethylrhodamine (TAMRA) cadaverine (full name: 5-(and-6-)-((N-(5-Aminopentyl)amino)carbonyl)tetramethylrhodamine) can be coupled to activated carboxy groups or sulfonyl chlorides.
TAMRA-PEO3-amine, TFA salt, 5 isomer
5-TAMRA-PEO3-amine (Tetramethylrhodamine-PEO3-amine) has a long water-soluble PEG spacer separating the dye and the amine functional group. The dye can be coupled to activated carboxy groups or sulfonyl chlorides.
