Alkynes, azides, BCN, and related reagents (27)
Alkyne reacts with azide to form 1,2,3-triazole by copper(I) catalyzed 1,3-dipolar Huisgen cycloaddition. BCN reacts with azide without copper calalysis. Available with bright and photostable CF dyes and biotin.
Amine-reactive dyes and related reagents (108)
Wide selection of succinimidyl ester dyes and biotin derivatives, for labeling proteins and other molecules with free amines, featuring bright and photostable CF dyes. Also available in antibody and protein labeling kits
Biotin derivatives and biotinylation reagents (50)
Biotin conjugated nucleotides and other probes, as well as biotin coupled to a selection of reactive groups for covalent conjugation to biomolecules.
Fluorescent dyes with an amine group (18)
Dyes with amine groups can react with activated carboxylic acid groups of biomolecules.
Maleimides and other thiol-reactive reagents (35)
Maleimide reactive groups can be used to label thiol groups of target molecules, such as cysteine residues in proteins.
Methanethiosulfonate (MTS) and thiosulfate (TS) probes (32)
Dyes and biotin derivatives with MTS or TS groups react with thiols at neutral pH. Negatively charged TS compounds can be used to specifically modify thiols on the surface of living cells.
Mix-n-Stain small ligand labeling kits (6)
Kits for rapid labeling of small ligands for cell surface or intracellular labeling; label with your choice of CF dyes in 30 minutes without a purification step.
Photoreactive probes (1)
