Biotin‐NHS ester

Product Description

Biotin‐NHS ester reagent enables simple and efficient biotin labeling of amine-containing organic molecules, antibodies, proteins and any other primary amine-containing biomolecules in solution. NH2-activated biotins require an organic solvent such as DMSO or DMF to be dissolved.

Formula: C14H19N3O5S

MW: 341.38 g/mol

Storage/Handling: Store at -20°C. Product shipped at ambient temperature.
Soluble in DMSO or DMF

Highlights:
- Biotin‐NHS ester reacts rapidly with any primary amine-containing molecule to attach the biotin label via
a stable amide bond.
- Biotin‐NHS ester is water insoluble - must be dissolved in DMSO or DMF before further dilution in
aqueous buffers.
- Spacer arm is 13.5 angstroms.
- High purity, crystalline biotin labeling reagents can be used to create high-quality biotin-labeled
derivatives biotinylation reagents.
