Amine-reactive dyes, biotin, and other related reagents (66)

Traditional fluorescent dyes, biotin and other reagents with a variety of amine-reactive groups; for dyes with superior fluorescence and photostability, see our CF dyes.

Dyes and biotin for labeling glycoproteins and other carbohydrates (5)

These reagents can react with an aldehyde or ketone group. Hydrazide reagents can also be used as fixable cell tracers; for dyes with superior fluorescence and photostability, see Biotium's CF dyes.

Dyes and biotin products containing an aliphatic primary amine (12)

These reagents can react with an activated ester, isothiocyanate or sulfonyl chloride group, or be used as cell tracers; for dyes with superior fluorescence and photostability, see our CF dyes.

Thiol-reactive dyes, biotin, and related reagents (39)

Reactive dyes as well as non-fluorescent modifying reagents for labeling cysteine residues in proteins and other thiol molecules.
