Preservative-free Annexin V conjugates are compatible with real-time staining of apoptotic cells for live cell imaging, fluorescence microscopy, or flow cytometry.

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

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

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® dyes with a BCN group react with azides via a copper-free bioorthogonal reaction to label target molecules for surface staining of live cells or cell extracts. Membrane-permeant CF® dye BCN conjugates for intracellular labeling reactions are also available.

Fluorescent CF® dye hydrazides are bright, extremely water-soluble, nontoxic molecules, useful as aldehyde-fixable cell tracers. They can also be used to label aldehyde or ketone groups of polysaccharides, carbohydrates or glycoproteins.

CF® dye picolyl azide derivatives fluorescently label alkyne groups on biomolecules via the standard azide-alkyne cycloaddition, but at low copper concentrations.

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.

Fluorescent CF® dye tyramides are used for tyramide signal amplification (TSA) for increasing immunofluorescence sensitivity in multicolor immunocytochemistry (ICC), immunohistochemistry (IHC), or in situ hybridization (ISH).

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, peptides or other molecules containing free thiol groups.

Labeled with our superior CF® dyes, dUTP conjugates can be used for TUNEL assay or to synthesize labeled DNA probes for in situ hybridization and nucleic acid blotting applications.

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.
