Merck, 71194-4, 0.5 M THP Solution

General description
Reducing agent compatible with HIS-BIND® chromatography
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 15 mM. THP is provided as a ready-to-use 0.5 M solution in water.

Purity: >80% by NMR. CAS: 4706-17-6. MW: 208.2.
Features and Benefits
Compatability with common methods for purifying His-tagged proteins - immobilized metal affinity chromatography with HIS-BIND® and Ni-NTA His•Bind resins at concentrations up to 1.0 mM

Stability: More stable and effective than traditional reducing agents like dithiothreitol (DTT)

Reducing Capacity: greater reducing capacity than TCEP against oxidized glutathione

Ready-to-use: THP is provided as a ready-to-use 0.5 M solution in water, making it easy to use in many applications with flexible usage
