Sulfo-NHS-Biotin
Sulfo-NHS-Biotin is a water-soluble biotinylation reagent frequently utilized in biochemical research for labeling proteins and other biomolecules. Chemically, it contains an N-hydroxysulfosuccinimide (Sulfo-NHS) ester group, allowing for covalent linkage through amine-reactive chemistry. Upon interaction with primary amines on lysine residues or peptide N-termini, the Sulfo-NHS ester undergoes nucleophilic attack, forming stable amide bond conjugates and releasing an NHS derivative. Its solubility in aqueous solutions facilitates direct addition to biological samples without prior dissolution in organic solvents. Common research applications include protein purification, affinity chromatography, immunoprecipitation assays, and detection in protein interaction studies.

• Protein labeling—biotinylate antibodies to facilitate immobilization, purification or detection using streptavidin resins or probes
• Cell surface labeling—do not penetrate the plasma membrane, biotinylates only surface proteins of whole cells
• Amine-reactive—reacts with primary amines (-NH2), such as lysine side-chains or the N-terminal-amine
• Solubility—charged sulfo-NHS group increases reagent water solubility compared to ordinary NHS-ester compounds
• Irreversible—forms permanent amide bonds; spacer arm cannot be cleaved
• Very short—spacer arm is 13.5 angstroms; it consists of the native biotin valeric acid group only

Applications |
Sulfo-NHS-biotin reagents were dissolved at 2 mM in a 50-mM K2HPO4/KH2PO4 buffer (pH 7.5) containing 50 mM of NaCl. They were immediately used in separated assays to modify 1.66 nmol of THUMPa protein. The labeling reactions were incubated 30 min at room temperature. The samples were then dialyzed for 15 min against a 50-mM K2HPO4/KH2PO4 buffer (pH 7.5) containing 50 mM of NaCl. TTotal biotin covalently bound to proteins was determined by an avidin-binding assay. |
