Fluorescent Proteins, Nucleotides & Other Conjugates

Biotin with TCO (trans-cyclooctene) reacts with tetrazine labeled molecule via copper free click chemistry.

Bright and photostable fluorescent BSA conjugates for applications in which well-defined molecular weight fluid phase tracers are needed. These applications include studying the rate of endocytosis and exocytosis and following vesicle trafficking.

Fluorescently labeled cAMP analogs that can be used to probe cAMP receptors.

CF® Dye labeled dextrans could be used as a fluorescent fluid-phase markers to study cell permeability, endocytosis, or mechanisms of biomolecular delivery. The dextran is 10,000 MW, and contains a formaldehyde-fixable free-amine group.

CF® Dye labeled dextrans could be used as a fluorescent fluid-phase markers to study cell permeability, endocytosis, or mechanisms of biomolecular delivery. The dextran is 150,000 MW, and contains a formaldehyde-fixable free-amine group; available with a selection of CF® Dyes.

This dextran is 250,000 MW, and contains a formaldehyde-fixable free-amine group; available with a selection of CF® dyes.

CF® Dye labeled dextrans could be used as a fluorescent fluid-phase markers to study cell permeability, endocytosis, or mechanisms of biomolecular delivery. The dextran is 3,500 MW, and contains a formaldehyde-fixable free-amine group.

This dextran is 40,000 MW, and contains a formaldehyde-fixable free-amine group; available with a selection of CF® dyes.

This dextran is 70,000 MW, and contains a formaldehyde-fixable free-amine group; available with a selection of CF® Dyes.

PNA lectin is a widely used histological fluorescent stain and is labeled with our superior CF® Dyes. It is specific for terminal β-galactose and binds preferentially to the commonly occurring structure, galactosyl (β-1,3) N-acetylgalactosamine.

CF®DI dye hydrazides react with carbonyl moieties of aldehyde or ketone groups. They are size- and charge-matched for detection of protein carbonylation by fluorescence two-dimensional differential gel electrophoresis (2D-DIGE).

Recombinant cholera toxin subunit B (CTB) purified from E. coli as a single, non-glycosylated polypeptide chain. Free of stabilizers and ready to conjugate.

Fluorescent conjugates of recombinant cholera toxin subunit B. Can be used for tract-tracing in neurological research, targeting GM1 ganglioside binding and retrograde transport.

A lectin labeled with our superior fluorescent CF® dyes is an effective and widely used cell surface stain for yeast, fungi, and mammalian cells.

Fluorescent dUTP can be used to synthesize labeled DNA probes for in-situ hybridization, microarray or blotting techniques.

Fluorescent cholera toxin subunit B (CTB) conjugates that are optimized for bright and clean staining of extracellular vesicles for flow cytometry.
