Single-Molecule Biolog (2 photos in total)y Core Lab

The main purpose of establishing the Single-Molecule Biology Core (SMBC) laboratory is to provide a user-friendly platform that bridges the gap between biology and biophysics. The biophysical experiments that are coordinated by the SMBC may be applied to many of the various interdisciplinary areas within Academia Sinica. The service encompasses several functions, including protein purification, determining the physical chemistry properties of fluorescence molecules, single-cell or single-molecule imaging, and probing the interactions between single molecules. Facilities for the SMBC have been adapted from an academician, Dr. Tao-Shih Hsieh's laboratory and are described below. The SMBC aims to maintain all of the unique facilities that were established by Dr. Hsieh and to provide a continued source of information, expertise, and service, which will allow researchers with complete or limited knowledge of these techniques to apply the methods to their research.

Brief Introduction of Single-Molecule Biology Core Facilities

Time-Resolved Confocal Fluorescence Microscopy, Micro Time 200 (PicoQuant), a commercial microscopy, allows us to record virtually all aspects of the fluorescence dynamics. With the TCSPC (Time-Correlated Single Photon Counting) method and the SymPhoTime software, MT200 cover broad research topics from biological, medical and chemical to physical sciences. The most prominent measurement and the analysis methods, including, FLIM (Fluorescence Lifetime Imaging), FCS (Fluorescence Correlation Spectroscopy), and FRET (FÖster Resonance Energy Transfer) are applicable under the current setup.

Total Internal Reflection Fluorescence Microscopy, TIRFM (Celltrif, Olympus)

Based on the objective-type of TIRF Microscopy, the incident angle of the excitation laser is adjusted through the back focal plane on the objective lens to induce the total internal reflection. Fluorescence molecules, which are close to the surface of coverslips within the evanescence wave propagating depth of 100 nm, can be observed. In the combination of fluorescence technique such as FRET, a variety of biological studies such as molecule interaction and protein folding/unfolding, dynamics of DNA, RNA, proteins, and large protein complexes, can be addressed. Following analysis of single molecule intensities and FRET trajectories, the structural dynamics of these molecules can be probed.

全內反射螢光顯微鏡

Apart from the single molecule measurement, TIRF microscopy can be used routinely on the imaging of membrane proteins, channels, and receptors that have the expression on the cell surface. Pharmacological analysis of ligand and receptor binding, and the tracking of the downstream cascade of signal transduction molecules, exocytosis and endocytosis of the neurotransmitters at chemical synapses, could also be fulfilled by the current TIRF setup.
