Biotin azide reacts with alkyne 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.

Biotin cadaverine free base (N-(5-Aminopentyl)biotinamide) can be directly coupled to activated carboxylic acid groups without using an additional base.

Biotin cadaverine, biotin-X cadaverine (90061), and biotin ethylenediamine (90057) can be coupled to carboxylic acids, DNA and other biomolecules.

Biotin ethylenediamine in free base form. White solid soluble in DMSO.

Biotin ethylenediamine iodoacetamide is readily coupled to thiols.

Biotin ethylenediamine, hydrobromide (N-(5-(6-((biotinoyl)amino)hexanoyl)amino)pentylmaleimide) is identical to Neurobiotin™, a useful anterograde and transneuronal tracer.

Biotin ethylenediamine, hydrochloride is functionally equivalent to Neurobiotin™ (biotin ethylenediamine, hydrobromide, 90057).

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.

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 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 SE (Biotin, succinimidyl ester) is readily coupled to a primary or secondary amine under mild conditions.

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.

Biotin-11-CTP (Biotin-11-cytidine-5′-triphosphate, tetralithium salt) can be enzymatically incorporated into RNA.

Biotin-11-dCTP (Biotin-11-2′-deoxycytidine-5′-triphosphate, tetralithium salt) can be enzymatically incorporated into DNA via nick translation, random priming, or 3′-end terminal labeling. The number 11 is the number of atoms in the linker between biotin and dCTP.
