Kits for succinimidyl ester labeling antibodies or other proteins with Biotium’s next-generation CF® dyes or biotin. 3 x 1 mg labeling reactions per kit.

CF® dye alkynes react with azide groups via copper-catalyzed bioorthogonal cycloaddition. Can be used to fluorescently detect or label azide groups on target molecules. CF® dye alkynes can also be used as building blocks to form fluorescent polymers.

CF® dyes with an aminooxy reactive group are useful for fluorescently labeling aldehyde or ketone groups on target molecules such as polysaccharids, glycoproteins or antibodies.

CF® dyes with an azide group. Can be used to label or detect alkyne, BCN or cyclooctyne-containing molecules by fluorescence spectroscopy, microscopy or flow cytometry following copper-catalyzed azide-alkyne cycloaddition.

CF® Dye Succinimidyl Esters (SE), also known as N-hydroxysuccinimide (NHS) esters are amine-reactive fluorescent dyes. They are commonly used to label primary amines of antibodies and other proteins, amine-modified oligonucleotides and other amine-containing molecules.

CF® Dye Maleimides are thiol-reactive fluorescent dyes. Maleimides are commonly used to label proteins, peptides or other molecules containing free thiol groups.

Easily label SNAP-tag®, CLIP-tag™, HaloTag®, or other ligands with fluorescent dyes, no purification needed. Cell membrane-permeant and impermeant dye options for intracellular or surface targets.
