THP [Tris(hydroxypropyl)phosphine; C₉H₂₁O₃P] is a water-soluble, odorless, sulfhydryl reducing agent that is more stable and effective than dithiothreitol (DTT). Against oxidized glutathione, the reducing capacity of THP (0.232 meq/g) is greater than that of TCEP (0.182 meq/g). THP is also more resistant to air oxidation than DTT and is compatible with immobilized metal affinity chromatography with His•Bind^® and Ni-NTA His•Bind resins at concentrations up to 1.0 mM. The common working concentration of THP for many applications is 1–5 mM. THP is provided as a ready-to-use 0.5 M solution in water.
