Polymer-modification and polymer solvent for the protein stabilization

Abstract

Electrochemical response of some heme-prtteins was analyzed with poly (ethylene oxide) (PEO) as protein modifier and solvent. These PEO-modified protein hybrids show electron transfer reactions in PEO without a drop of water. Extremely high thermal stability on the redox reaction, such as at 130°C for 30min., was confirmed. This thermal stabilization was analyzed to be induced by the use of PEO as a solvent.
