Annexin V fluorescent conjugates can be used to detect apoptotic cells. Annexin V is available labeled with our superior near-IR fluorescent dyes.

This kit contains everything you need to label antibodies or other proteins with a fluorescent CF® dye succinimidyl ester (CF® dye SE) or biotin succinimidyl ester (biotin SE). Each kit contains reagents for three labeling reactions of up to 1 mg protein per reaction.

Aminooxy dyes have an aminooxy reactive group, which can be used to label a target molecule with an aldehyde or ketone group. An aminooxy group readily reacts with an aldehyde or ketone group to form a stable linkage without the use of a reducing agent.

CF® dye with BCN reacts with azide to form 1,2,3-triazole by copper-free 1,3-dipolar Huisgen cycloaddition. This copper-free bioorthogonal reaction allows staining the surface of live cells or cell extracts when there are concerns about native protein function loss with copper. We also offer membrane-permeant CF® dye BCN options for intracellular reaction.

CF® Dye Succinimidyl Esters (SE, also known as NHS esters) are amine-reactive fluorescent dyes. SE dyes are commonly used to label antibodies and other proteins on free amine groups, such as lysine residues.

CF® dye-dUTP can be used for TUNEL assay, or to synthesize labeled DNA probes for in situ hybridization and nucleic acid blotting applications.

Mix-n-Stain™ antibody labeling kits are a revolutionary antibody labeling technology that allows you to label your antibody with one of our superior CF® dyes in 30 minutes without a purification step. The labeling procedure tolerates many common buffer components and antibody stabilizers. Now with an extended shelf life of at least 1 year.

Mix-n-Stain™ small ligand labeling kits are designed for rapid labeling of low molecular weight (MW approx. 150 -5000) and relatively high affinity biological ligands (or substrates) without a purification step.

Near-IR CF® dye free acids are control dyes for studies that involve CF® dye succinimidyl ester conjugated to antibody, protein or peptides.  Available with the following CF® dyes: CF®680, CF®750, CF®770, and CF®790.

This labeling kit comprises our superior near-IR amine-reactive CF® dye and other components necessary for carrying out antibody labeling and purification. It’s available with the following CF® dyes: CF®680, CF®750, CF®770, and CF®790.

Conjugates of α-Bungarotoxin labeled with a selection of our CF® dyes and other labels. Labeled α-bungarotoxin conjugates can be used for staining nicotinic acetylcholine receptors at neuromuscular junctions in tissue sections.

CF® dye bovine serum albumin (BSA) are 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.

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.

This product is concanavalin A (Con A) labeled with our superior fluorescent CF® dyes. Con A is a widely used lectin that selectively binds to a-mannopyranosyl and a-glucopyranosy residues, found in the cell wall of yeast and fungi, and the cell membrane of mammalian cells.

This product is prepared by labeling highly cross-adsorbed donkey anti-goat IgG (H+L) with a selection of our bright and photostable CF® dyes and other labels. To minimize cross-reactivity, the antibody has been adsorbed against chicken, guinea pig, Syrian hamster, horse, human, mouse, rabbit, and rat serum.
