Summary

Automatic Translation

Automatic Translation

Protokol her beskriver renset hEAG1 ion-kanal protein interaktioner med lille molekyle lipid ligand phosphatidylinositol 4, 5-bisfosfat (PIP2). Målingen viser, at BLI kunne være en potentiel metode til romanen små-molekyle ion-kanal ligand screening.
