This book was released on 2017 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluorescence microscopy has proven to be immensely powerful for the study of biological systems at both the cellular and systems biological levels. The ability to specifically label a single molecular species fluorescently has enabled the study of complex cellular structures through the visualization of their constituent components both individually as well as in context of the overall structure. Since the advent of engineered fluorescent proteins (such as GFP) and other proteins capable of being genetically encoded as fusion constructs, the utility of fluorescence microscopy has increased exponentially in terms of the ability to efficiently, specifically label desired molecules while limiting perturbations to the biology under study. With this enhanced ability of visualization came a hand-in-hand evolution of computational techniques to extract quantitative information from microscopy images. In this thesis, I focus on the application of fluorescence imaging at the biophysical level in living cells: analyzing the motion/dynamics of single molecules and complexes, which are small relative to the structures of the cell, in order to elucidate their molecular function and mechanism. The motion of these "particles" within living cells is necessarily related to their functions as well as their interacting partners, which can vary dynamically during their lifetimes. Observation and analysis of this motion using a combination of fluorescence microscopy and robust quantitative analysis allows one to infer these characteristics. Here, I study three diverse biological systems in the context of live-cell fluorescence microscopy and biophysical analysis: 1) the transport of 0-actin mRNA particles in primary mouse neurons, 2) kinetochore motion during cell division, specifically focusing on anaphase dynamics, and 3) the motion of cell-growth-implicated membrane proteins in Bacillus subtilis.

Download or read book Single Molecule Fluorescence Spectroscopy of the Folding of a Repeat Protein written by Sharona Cohen and published by Springer. This book was released on 2015-10-17 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis single-molecule fluorescence resonance energy transfer (FRET) spectroscopy was used to study the folding of a protein that belongs to the large and important family of repeat proteins. Cohen shows that the dynamics of the expanded conformations is likely to be very fast, suggesting a spring-like motion of the whole chain. The findings shed new light on the elasticity of structure in repeat proteins, which is related to their function in binding multiple and disparate partners. This concise research summary provides useful insights for students beginning a PhD in this or a related area, and researchers entering this field.

Download or read book Measuring Conformational Dynamics of Biological Molecules with Single molecule Tracking and Fluorescence Correlation Spectroscopy written by Charles Limouse and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The past two decades have seen great advances in single-molecule techniques capable of probing biomolecular systems with spatial resolution down to the nanometer level. However few techniques are specifically designed to measure larger scale organization between a few tens and a few hundreds of nanometers, especially when other figures of merit are considered, such as high time-resolution or the possibility to do measurements in bulk and without immobilization. Such features would be particularly useful in the study of molecular structures like chromatin or other nucleoprotein complexes, that exhibit organizational details and dynamics across a broad range of time and length scales. I present how the combination of fluorescence correlation spectroscopy (FCS) and single molecule tracking can be used to measure the conformational dynamics of molecules that diffuse freely in solution, at the scale of a few tens of nanometers. I discuss some aspects of the instrumentation as well as the parameters that define the spatial and temporal resolution. I describe other advantages of the technique such as the possibility to bypass a common difficulty associated with fluorescence correlation measurements and obtain a signal that is not convolved with the blinking dynamics of the fluorescent probe itself. Finally I present an experimental proof-of-principle where tracking-FCS was applied to measure the end-to-end Brownian dynamics of short DNA fragments in the semilflexible regime.
Download or read book An Introduction to Fluorescence Correlation Spectroscopy written by Thorsten Wohland and published by Iop Expanding Physics. This book was released on 2020-11-04 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Introduction to Fluorescence Correlation Spectroscopy represents a comprehensive introduction to fluorescence correlation spectroscopy (FCS), a biophysical experimental technique increasingly used to study and quantify molecular mobility, concentrations and interactions in vitro, as well as in living cells and multicellular organisms. Students and researchers who are new to FCS can use the book as the first introduction to the technique, while those who are already using FCS regularly in their research may find it useful to deepen their understanding of the technique, its possibilities, limitations, and potential pitfalls as well as ways to avoid them. This book introduces the reader to all aspects of FCS needed for practical usage of the technique in their research. In the beginning the concept of fluorescence intensity fluctuations and their auto- and cross-correlation functions are explained to give readers an understanding of the underlying principles. This is followed by an overview of instrumental FCS setups and various ways of data collection and processing, the derivations of theoretical models relating the experimentally obtained correlation functions to the underlying molecular processes, and the description of the fitting of experimental data with those models. Mathematically more involved portions are separated from the rest of the text and can be easily skipped by readers more interested in the conceptual and practical aspects of FCS. The book contains interactive graphics and is accompanied by an interactive computable document file allowing the reader to test the dependence of FCS results on a variety of experimental parameters, and to gain practical insights into FCS data fitting. Key Features Introduces the concepts of FCS in an accessible way, supported by animations and graphics in the ebook. Includes a supplementary interactive computable document file that allows the reader to experiment with various FCS setup and fit parameters, allowing readers to test their understanding and simulate experimental outcomes. Provides rigorous mathematical derivations of fundamental FCS equations and models. Pedagogical features include questions, short reviews and critical discussions of literature relevant to the particular chapter that include applications and fundamental developments in the field of FCS.

Download or read book Molecular Dynamics And Spectroscopy By Stimulated Emission Pumping written by Hai-lung Dai and published by World Scientific. This book was released on 1995-06-29 with total page 1137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the first stimulated emission pumping (SEP) experiments more than a decade ago, this technique has proven powerful for studying vibrationally excited molecules. SEP is now widely used by increasing numbers of research groups to investigate fundamental problems in spectroscopy, intramolecular dynamics, intermolecular interactions, and even reactions. SEP provides rotationally pre-selected spectra of vibrationally highly excited molecules undergoing large amplitude motions. A unique feature of SEP is the ability to access systematically a wide variety of extreme excitations localized in various parts of a molecule, and to prepare populations in specific, high vibrational levels. SEP has made it possible to ask and answer specific questions about intramolecular vibrational redistribution and the role of vibrational excitation in chemical reactions.
