| | The Si-tag for Immobilizing Proteins on a Silicon Device | | Authors: | A. Kuroda | | Affilation: | Hiroshima University, JP | | Pages: | 571 - 574 | | Keywords: | protein, immobilization, biosensors, supramolecular assemblies | | Abstract: | Targeting functional proteins to specific sites on a silicon device is essential for the development of new biosensors and supramolecular assemblies. Recently, we found ribosomal protein L2 as a silicon-binding protein, which can be used to immobilize fused proteins on a silicon device. Indeed, a fusion of L2 and green fluorescence protein (GFP) adsorbed to the silicon/silica particles with a Kd of 0.7 nM at pH 7.5. This fusion protein was retained on the silicon device even after washing for 24 h with a buffer. A fusion of L2 and firefly luciferase also functionally adsorbed on the silicon device. This L2, which we call the Si-tag, can be used for one-step targeting of functional proteins on a silicon device without chemical modification of the surface. | | ISBN: | 1-4200-6376-6 |
