Reactive CF® Dyes, Other Reactive Dyes & Biotinylation Reagents

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.

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.
