Biotin & Streptavidin Conjugates

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.

Biotin-16-UTP can be enzymatically incorporated into RNA. The number 16 indicates the number of atoms between biotin and UTP.

This product is similar to biotin-11-dUTP (40029) and biotin-16-dUTP (40022) except that it has a longer and water-soluble spacer group, which should facilitate interaction between the biotin group and avidin or streptavidin.

This product is similar to biotin-11-dUTP (40029) and biotin-16-dUTP (40022) except that it has a longer and water-soluble spacer group, which should facilitate interaction between the biotin group and avidin or streptavidin.

This product is similar to biotin-11-UTP (40033) and biotin-16-UTP (40023) except that it has a longer and water soluble spacer group, which should facilitate interaction between the biotin group and avidin or streptavidin.

Biotin-4-fluorescein (N-(5-aminopentyl)biotinamide, trifluoroacetic acid salt) has been reported to be a superior fluorescent biotin derivative for accurate measurement of avidin and streptavidin in crude biological samples. Binding of biotin to avidin and streptavidin is high affinity, fast and noncooperative.

Biotin-AM3-25 is a conjugate of AM3-25 and biotin. Membranes labeled with the probe can subsequently couple to avidin or streptavidin.

A biotin-conjugated cAMP analog that can be used to probe cAMP receptors.

A biotinylated cyclic nucleotide that is an important second messenger in many biological processes and has been used as a tracer in immunoassays.

Biotin-DHPE (N-(Biotinoyl)-1,2-dihexadecanoyl-sn-glycero-3-phosphoethanolamine, triethylammonium salt) can be used to couple avidin or streptavidin to cell membranes or liposomes.

Biotin-PEO₂-PPO₂-amine trifluoroacetic acid (TFA) salt is a water soluble biotin derivative with an amine group.

Biotin-PEO₃-amine is a water soluble biotin derivative that can be readily coupled to activated carboxylic acids.

Biotin-PEO₄-amine is a water soluble biotin derivative that can be readily coupled to activated carboxylic acids.

Biotin-PEO₄-hydrazide is a water-soluble biotin derivative capable of reacting with aldehydes or ketones to form hydrazones.

Biotin-PEO₄-maleimide is a water soluble biotin derivative that can be readily coupled to thiols.

Biotin-PEO₄-propionate SE (Biotin-PEO₄-propionate succinimidyl ester) is a water soluble biotin derivative that can be readily coupled to primary or secondary amines.
