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.
