Biotin & Streptavidin Conjugates

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.

Biotin-11-dUTP 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 dUTP.

Biotin-11-dUTP 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 dUTP.

Biotin-11-UTP can be enzymatically incorporated into RNA. The number 11 is the number of atoms in the linker between biotin and UTP.

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-16-dUTP can be enzymatically incorporated into DNA via nick translation, random priming, or 3′ end terminal labeling. The terminal deoxynucleotidyl transferase (TdT)-mediated biotin-dUTP nick end-labeling (TUNEL) method has been commonly used for apoptosis studies.
