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.
