WebLabeling Proteins with ATTO NHS-Esters ATTO NHS-esters readily react with amino groups of proteins. The optimum pH-range for NHS-ester coupling is pH 8.0 – 9.0. At this pH amino groups of proteins, i.e. the ε-amino groups of lysines are unprotonated to a degree sufficiently high for fast coupling. Required Materials WebAn NHS ester may be formed by the reaction of a carboxylate with NHS in the presence of a carbodiimide. To prepare stable NHS ester derivatives, the activation reaction must be performed in nonaqueous conditions using water-insoluble carbodiimides or condensing agents, such as DCC, or, better, an uronium-based activation agent ( Chapter 4, Section …
