Reactive CF® Dyes, Other Reactive Dyes & Biotinylation Reagents

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 polysaccharides, glycoproteins or antibodies.

TS biotin ethylenediamine (Biotin ethylenediamine thiosulfate, sodium salt) is a highly selective thiol labeling probe. Similar to the MTS group, TS (thiosulfate) group is capable of reacting with thiols at nearly neutral pH.

CF® Dyes with a reactive amine group to fluorescently label carboxylic acid groups in proteins and other molecules.

MTSEA biotin selectively labels thiols under mild conditions. It’s available in 3 variations: Biotin, Biotin-X, and Biotin-XX, all of which allow selective labeling of cell surface thiols.

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.

Kits for labeling & purification of near-IR antibody conjugates for small animal in vivo imaging, featuring Biotium’s industry-leading near-IR CF® Dyes.

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.
