Biotin‐NHS ester B-120-100

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.
