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 alkyne reacts with azide to form 1,2,3-triazole by copper(I) catalyzed 1,3-dipolar Huisgen cycloaddition. It can also be used as a monomer to copolymerize with other monomers to form fluorescent polymers.

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 azide reacts with alkyne to form 1,2,3-triazole by copper(I) catalyzed 1,3-dipolar Huisgen cycloaddition. It could also undergo Staudinger ligation with a phosphine containing compound.

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 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.

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.

Highly cross-adsorbed donkey anti-guinea pig IgG (H+L) labeled with our bright and photostable CF® dyes. To minimize cross-reactivity, the antibody has been adsorbed against bovine, chicken, goat, Syrian hamster, horse, human, mouse, rabbit, sheep and rat serum.

This product is prepared by labeling highly cross-adsorbed donkey anti-mouse 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 bovine, chicken, goat, guinea pig, Syrian hamster, horse, human, rabbit, and sheep serum.

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

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

This product is prepared by labeling highly cross-adsorbed goat anti-chicken IgY (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 bovine, goat, guinea pig, Syrian hamster, horse, human, mouse, rabbit, rat, and sheep serum.

Goat anti-llama secondary antibody is available conjugated to a selection of our bright and photostable CF® dyes or HRP.
