Sulfo-NHS Acetate Supplier

Product name:Sulfo-NHS Acetate
Molecular formula: C6H6NNaO7S
Molecular weight:259.17
Description of Sulfo-NHS Acetate:
Chemical name:Sulfosuccinimidyl Acetate
Form: White to off-white powder, free of foreign material
Solubility: 10mM produces a clear and colorless solution
Storage temp.: 0-6°C
 Sulfo-NHS-Acetate is a small compound used for blocking primary amines (e.g., lysine side chains). This compound forms stable, covalent amide bonds with amine groups to prevent specific interactions or conjugations.
Sulfo-NHS-Acetate is typically used to prevent polymerization when performing protein crosslinking reactions and when conjugating peptides to carrier proteins for immunogen production. Blocking amines on the peptide allows directed conjugation of carboxylic acids on the peptide to primary amines on the protein using EDC.
