Sulfo-NHS-LC-Biotin

KEY FEATURES: • Amine-reactive; has a spacer with arm length of 22.4 Å which helps to minimize steric hindrance to biotin labeling • More water-soluble than the corresponding NHS compound without the sulfo group • Membrane-impermeable • Forms permanent amide bonds and the spacer arm cannot be cleaved APPLICATIONS: • Sulfo-NHS-LC-Biotin is ideal for biotinylating antibody or protein that can then be used for protein detection, purification or immobilization • Sulfo-NHS-LC-Biotin is particularly useful for targeting cell surface proteins due to the membrane-impermeability of this reagent
