제목 Green Fluorescent Protein Adsorption with Metal Organic Framework-coated Quartz Crystal Microbalance Plate
초록 Interaction of Oligohistidine-tags(His-tag) with metal ions have long have been known and used for various purposes. Here, we report a method for attaching His-tagged proteins to a Metal Organic Framework(MOF)-coated Quartz Crystal Microbalance(QCM) plate. QCM is capable of detecting nanogram-scale mass change with a simple procedure, giving immediate quantitative results. Especially, MOF-coated QCM is predicted to have increased efficiency in mass-change sensitivity. In this research, we selected MOF candidates with metal ions that are known to interact strongly with his-tags and coated them on the QCM plate. For determining the interaction with his-tagged proteins, we applied His-tagged Green Fluorescent Protein(GFP) to the MOF film and observed the color change with a UV microscope, having successful results. This opens a new possibility for using His-tagged protein attached MOF QCM as a tunable sensor, depending on what receptor we utilize as a protein.
