Label your antibody with biotin in just 15 minutes without a purification step. Labeling tolerates many common buffer components including BSA and ascites.

Aminooxy-biotin can be used to covalently attach biotin to aldehyde or ketone groups on polysaccharides, glycoproteins or antibodies. Aminooxy-biotin has also been used to efficiently label cell-surface glycans on living animal cells.

Digoxigenin-dUTP can be enzymatically incorporated into DNA via nick translation, random priming, or 3′-end terminal labeling to synthesize labeled DNA probes for in-situ hybridization, microarray or blotting techniques.  The digoxigenin labeled probe could be detected by using fluorescent labeled or enzyme labeled anti-digoxigenin antibody.

Biotin picolyl azide reacts with alkyne to form 1,2,3-triazole by 1,3-dipolar Huisgen cycloaddition through the use of a much lower copper (I) concentration without sacrificing reaction efficiency.

TMR biocytin is a cell-impermeant, fixable polar tracer that combines the tetramethylrhodamine (TAMRA) with biotin and an aldehyde-fixable primary amine.  Polar tracers are commonly used to investigate cell-cell and cell-liposome fusion as well as membrane permeability and transport through gap junctions or cell uptake during pinocytosis.

DEAC-dUTP (diethylaminocoumarin-dUTP) can be used to synthesize fluorescent DNA probes for in situ hybridization, microarray or blotting techniques. DEAC has absorption at 426 nm and emission at 480 nm.

Fluorescein-12-dUTP can be used to synthesize fluorescent DNA probes.

Biotin-XX tyramide conjugate can be used for tyramide signal amplification (TSA) to generate high-density labeling of a target protein or nucleic acid with biotin.

Biotin azide reacts with alkyne to form 1,2,3-triazole by copper(I) catalyzed 1,3-dipolar Huisgen cycloaddition.

Biotin alkyne reacts with azide to form 1,2,3-triazole by copper(I) catalyzed 1,3-dipolar Huisgen cycloaddition.

Biotin BCN, an alternative to biotin labeled DIBO and DBCO, reacts with azide to form 1,2,3-triazole by copper free 1,3-dipolar Huisgen cycloaddition.

CF®640R-UTP can be enzymatically incorporated into RNA probes for use in many biological applications.

BrdU (5-Bromo-2′-deoxyuridine) can be incorporated into DNA during cell division and subsequently detected by a BrdU antibody. The probe can be used to study cell-cycle kinetics (1).
