Advanced Fluorescence Correlation Spectroscopy for Measuring Molecular Conformation and Dynamics

3/22/2021
University Göttingen
Wilhelmsplatz 1, 37073 Göttingen, Germany

Jörg Enderlein

III. Institute of Physics - Biophysics, Georg-August-University Göttingen

This webinar is co-organized by Dr. Gilad Haran, Chair of the Biophysical Society’s Biological Fluorescence Subgroup.

The development of single molecule spectroscopy (SMS) had an enormous impact on many biophysical studies by allowing to measure full distributions of molecular parameters, instead of only average values as usually determined by ensemble measurements. One specific technique of SMS is fluorescence correlation spectroscopy (FCS) which evaluates the fluorescence intensity fluctuations observed out of a femotliter-sized confocal detection volume. Thus allows to measure molecular size and concentration of fluorescently tagged molecule at pico- to nanomolar concentrations, but also to resolve conformational dynamics and conformational transitions with a temporal resolution down to a few nanoseconds. I will present a general introduction into FCS and will then focus on several of its advanced variants. In particular, I will introduce dual-focus or 2fFCS, which allows for precise calibration-free molecular sizing. Next, fluorescence lifetime correlation spectroscopy (FLCS) will be presented which is a powerful tool for resolving intramolecular conformational fluctuations. Then, I will discuss photoelectron transfer or PET-FCS, which is a simple but powerful complement to single-molecule Förster resonance energy transfer (smFRET) when studying conformational fluctuations in intrinsically disordered proteins. Finally, I will discuss FCS on a pico- to nanosecond timescale, where it provide valuable information about molecular rotational diffusion and molecular stoichiometry (fluorescence antibunching).


Annual Probst Lecture Series

3/25/2021
1 Hairpin Dr, Edwardsville, IL 62026
Southern Illinois University Edwardsville

Featuring Dr. Karen Fleming
"Bacterial Hot Potato"

The Department of Chemistry of Southern Illinois University Edwardsville (SIUE) initiated the Probst Lecture series in 1975 as a memorial to one of its founding faculty members, Professor William J. Probst. Each year a noted chemist is invited for a visit that features several lectures. An evening lecture usually consists of a topic that is broad in scope to attract the interest of alumni, faculty, and students throughout the arts and sciences, while a second afternoon lecture focuses on the guest's contributions to chemical research. 

Dr. Karen Fleming is a Professor in the T.C. Jenkins Department of Biophysics at Johns Hopkins University. She is a leader in the field of membrane protein biophysics, which aims to describe biochemical and biological processes using physical principles. Her work has enabled the fundamental understanding of processes underlying protein folding. Her work focuses on understanding this phenomenon in membrane proteins, which are notoriously challenging to work with. Her achievements in this field have helped scientists understand how membrane proteins partition across cell membranes by establishing a novel hydrophobicity scale that helps predict their behavior. Aside from the many advisory positions she has held, Karen also received numerous awards and honors having been recognized with the Department of Defense Career award and the Thomas E. Thompson award in 2016 from the Biophysical Society. In addition to her scientific accomplishments she is also a strong proponent of diversity and the ongoing issues affecting the STEM fields. She was recently awarded the Provost’s Faculty Diversity Prize in 2019 for her efforts advocating for underrepresented groups.

Biophysical Society of Japan - Proteins in Motion! Poster Share

3/22/2021 - 3/26/2021
Biophysical Society of Japan
Miyagi, Japan

Our body consists of many different organs, such as the muscle, heart, eye, and brain. Each organ is made up of many cells. Looking inside a magnified cell, you can see it is full of tiny proteins with sizes of only one hundred-thousandth of a millimeter.

Proteins within our body are dynamic and constantly moving as they carry out specific functions. For example, some proteins rotate to create energy, others walk along filaments to deliver cargo, or dock to transfer materials from the extracellular world. Motion of the proteins is essential to carry out cellular processes needed for life!

Share this poster with your colleagues, students, and friends.

Biophysics, Past, Present and Future Perspectives - And Some Recent Insights Into Water in Receptor

3/23/2021
Vilnius University
Lithuania

Lithuanian Biophysical Society for the first time celebrarates International Biophysics Week. We are very proud to invite you to a lecture “Biophysics, past, present and future perspectives - and some recent insights into water in receptor action“ by the past president of EBSA (European Biophysical Societies' Association) Prof. Anthony Watts (University of Oxford).    Biophysics is called the “bridging science”; bridging physics, theory and modelling to biology. It could be argued that as far back as the early civilizations, any physical phenomenon that has been applied to investigate or exploit biology, is biophysics. Hooke’s development of microscopes or Newton’s primitive spectroscopy, and much more, cannot be ignored, any more than 20th century contemporary molecular biophysics. A brief history of biophysics and some crystal ball gazing for the development of the field, will be followed by a description of water involvement in receptor activation/desensitization from recent high resolution structural studies.    

The event will be moderated by the Chair of Lithuanian Biophysical Society Prof. Saulius Šatkauskas. The lecture will be held in English on March 23rd 12:00 EET on Microsoft Teams.    

All are welcome!

Centrality and Community Detection in Dynamic Residue Networks

3/26/2021
Sabanci University
Istanbul, Turkey

Being a widely used centrality measure for residue networks (RNs), betweenness  centrality (BC) is informative about evolutionary and functional features of a protein  structure. Communities as close-knit amino-acid groups are detected with Girvan-  Newman algorithm, which is an edge BC based method. Hence, in the lens of  centrality and community, dynamic conformations of a protein are scrutinized to  understand the effect of mutation and/or binding. In this single day "Dialogues in the MIDST" event which is now a Biophysics Week regular, the morning session will be devoted to the theoretical aspects of centrality/community concepts in RNs and their meaning in terms of biophysical applications. In the afternoon, there will be a hands-on session with coding and applying the ideas to the favorite protein of each attendee using Python programming language along with Q&A and discussions.    


Correlating Analytical Microscopy (AFM, EM & EDS) for Biological Research

3/24/2021
Oxford Instruments Demo Facility
High Wycombe, Buckinghamshire, United Kingdom

Correlative microscopy enables biologists to investigate features of their sample using the strengths of different types of microscope. Usually, correlative microscopy in biology features light microscopy, electron microscopy and sometimes x-ray microscopy. It is now also possible to correlate materials properties, using atomic force microscopy, and chemical analysis, using energy dispersive x-ray spectrometry (EDS/EDX) with more traditional forms of microscopy, extending out understanding of the chemical and physical properties of our specimens.   Our webinar will introduce AFM and EDS applications within biological research and demonstrate the acquisition of correlative data, including the challenges surrounding sample preparation and finding the same region on the samples. We will then explore how to analyse quantitative measurements and images acquired from correlative microscopy. The webinar will be followed by a question-and-answer session with the presenters.
