Annexin V fluorescent conjugates can be used to detect apoptotic cells. Annexin V is available conjugated to a wide variety of 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.

CF® Dye Amines can be used to conjugate CF® dyes to carboxylic acids groups in biological molecules.

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.

Our CF® dye hydrazides are bright, extremely water-soluble and nontoxic. These properties make the dyes excellent fixable polar tracers for neurons, or for gap junction studies.

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.

Potential applications of Biotin-CF® dye include detection of biotin binding sites and the degree of biotinylation of proteins, and for the measurement of avidin and streptavidin in crude biological samples. In addition, biotin-CF® dye can be used as a polar tracer by microinjection to study the morphology of cells.

CF® Dye Maleimides are thiol-reactive fluorescent dyes. Maleimides are commonly used to label proteins on free thiol groups.

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.

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.

This product is bovine anti-goat IgG labeled with our superior CF™ dyes. The antibody is created by immunizing a cow host with goat IgG to minimize the reactivity for bovine IgG. The antibody has been adsorbed against bovine, chicken, guinea pig, Syrian hamster, horse, human, mouse, rabbit and rat serum proteins.

This product is prepared by labeling an affinity-purified chicken anti-goat IgG (H+L) with a selection of our bright and photostable CF® dyes, or other labels.

This product is prepared by labeling an affinity-purified chicken anti-mouse IgG (H+L) with a selection of our bright and photostable CF® dyes.

This product is prepared by labeling an affinity-purified chicken anti-rabbit IgG (H+L) with a selection of our bright and photostable CF® dyes.

Cholera toxin B subunit is used for tract-tracing in neurological research, targeting GM1 ganglioside binding and retrograde transport. CF® dyes offer exceptional brightness and photostability.
