磺基-NHS-LC-生物素(1套(10 x 1毫克))產(chǎn)品是KEY FEATURES:n? Amine-reactive; has a spacer with arm length of 22.4 A? which helps to minimize steric hindrance to biotin labelingn? More water-soluble than the corresponding NHS compound without the sulfo groupn? Membrane-impermeablen? Forms permanent amide bonds and the spacer arm cannot be cleavednAPPLICATIONS:n? Sulfo-NHS-LC-Biotin is ideal for biotinylating antibody or protein that can then be used for protein detection, purification or immobilization n? Sulfo-NHS-LC-Biotin is particularly useful for targeting cell surface proteins due to the membrane-impermeability of this reagent
