Biotinylation Reagents
A selection of biotin reagents with a full selection of functionalized reactive groups, for biotinylation of biological molecules, or for use as cytoplasmic or neuronal tracers. Also see our bright and photostable CF® Dye Anti-Biotin and Streptavidin Conjugates.
Biotin NTA
Biotin NTA, also known as BNTA (Biotin nitrilotriacetic acid, tripotassium salt) is used to detect histidine-tagged proteins (as little as 0.1 pmol) immobilized on nitrocellulose membranes.
Biotin-X NTA
Biotin-X NTA (Biotin-X nitrilotriacetic acid, tripotassium salt) is used to detect histidine-tagged proteins (as little as 0.1 pmol) immobilized on nitrocellulose membranes.
Biotin TCO
Biotin with TCO (trans-cyclooctene) reacts with tetrazine labeled molecule via copper free click chemistry.
Biotin Methyltetrazine
Biotin with methyltetrazine reacts with cyclooctene (TCO, methylcyclopropene) labeled molecule via copper free click chemistry.
Aminooxy-biotin
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.
Biotin Picolyl Azide
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.
Biotin Azide
Biotin azide reacts with alkyne to form 1,2,3-triazole by copper(I) catalyzed 1,3-dipolar Huisgen cycloaddition.
Biotin Alkyne
Biotin alkyne reacts with azide to form 1,2,3-triazole by copper(I) catalyzed 1,3-dipolar Huisgen cycloaddition.
Biotin BCN
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.
Biotin-PEO4-maleimide
Biotin-PEO4-maleimide is a water soluble biotin derivative that can be readily coupled to thiols.
Biotin-PEO4-hydrazide
Biotin-PEO4-hydrazide is a water-soluble biotin derivative capable of reacting with aldehydes or ketones to form hydrazones.
Biotin-12 SE
Biotin-12 SE is an amine-reactive biotin derivative with a long spacer group. It is useful for making biotin labeled nucleoside triphosphates among other applications.
Biotin-x cadaverine, free base
Biotin-X cadaverine (5-(((N-(Biotinoyl)amino)hexanoyl)amino) pentylamine, free base) can be coupled directly to activated carboxylic acid esters without the use of a base.
Biotin-PEO2-PPO2-amine, TFA salt
Biotin-PEO2-PPO2-amine trifluoroacetic acid (TFA) salt is a water soluble biotin derivative with an amine group.
Biotin cadaverine, free base
Biotin cadaverine free base (N-(5-Aminopentyl)biotinamide) can be directly coupled to activated carboxylic acid groups without using an additional base.
Biotin-PEO4-amine
Biotin-PEO4-amine is a water soluble biotin derivative that can be readily coupled to activated carboxylic acids.
