| Outline of Final Research Achievements |
In order to establish novel method that can immobilize membrane proteins into gel materials without protein denaturation, we studied development of novel chemically reactive-solubilization surfactants for membrane proteins and construction of 3D gels encapsulating membrane protein by using the above reactive-solubilization surfactants. The reactive-solubilization surfactants were designed from DKDKC12K; the mono-alkyne-modified DKDKC12K, Alk-DKDKC12K, and the bis-modified Bis-Alk-DKDKC12K were prepared, respectively. By an in situ cross-linking reaction of Bis-azide-PEG derivatives with Alk-DKDKC12K or Bis-Alk-DKDKC12K on binding to membrane integral domain of membrane proteins in an aqueous buffer, we succeeded in making gelation of membrane proteins without protein denaturation. By applying the above gelation process to 3D printing techniques, we also succeeded in construction of 3D-structured gels encapsulating membrane proteins.
