Single-Molecule Assay for Proteolytic Susceptibility: Force-Induced Collagen Destabilization [PDF]

open access: yesBiophysical Journal, 2018
Force plays a key role in regulating dynamics of biomolecular structure and interactions, yet techniques are lacking to manipulate and continuously read out this response with high throughput. We present an enzymatic assay for force-dependent accessibility of structure that makes use of a wireless mini-radio centrifuge force microscope to provide a ...

Protocol for live-cell super-resolution imaging of transport of pre-ribosomal subunits through the nuclear pore complex

open access: yesSTAR Protocols
Summary: Here, we present a protocol for single-molecule super-resolution imaging of the nuclear export of pre-ribosomal subunits pre-40S and pre-60S through nuclear pore complexes. We describe steps for plating cells and co-transfecting cells.

An automated Bayesian pipeline for rapid analysis of single-molecule binding data

open access: yesNature Communications, 2019
Analysis of single-molecule binding assays still requires substantial manual user intervention. Here, the authors present a pipeline for rapid, automated analysis of co-localization single-molecule spectroscopy images, with a modular user interface that ...

Observing protein dynamics during DNA-lesion bypass by the replisome

open access: yesFrontiers in Molecular Biosciences, 2022
Faithful DNA replication is essential for all life. A multi-protein complex called the replisome contains all the enzymatic activities required to facilitate DNA replication, including unwinding parental DNA and synthesizing two identical daughter ...

Immunofunctional assay of human growth hormone (hGH) in serum: A possible consensus for quantitative hGH measurement [PDF]

open access: yes, 1996
Confirmation of the diagnosis of GH deficiency in adults and children involves provocative testing for human (h) GH. Different commercially available immunoassays yield largely discrepant results in the measurement of GH levels in human serum.

Rho-dependent transcription termination proceeds via three routes

open access: yesNature Communications, 2022
Rho is a general transcription termination factor in bacteria. Here, Song et al. use single-molecule fluorescence assays to provide evidence that Rho-mediated transcription termination can occur via three kinetically different routes.

Single-Molecule Imaging in Living Plant Cells: A Methodological Review

open access: yes, 2021
Single-molecule imaging is emerging as a revolutionary approach to studying fundamental questions in plants. However, compared with its use in animals, the application of single-molecule imaging in plants is still underexplored.

Single-molecule and single-particle imaging of molecular motors in vitro and in vivo.

open access: yes, 2014
Motor proteins are multi-potent molecular machines, whose localisation, function and regulation are achieved through tightly controlled processes involving conformational changes and interactions with their tracks, cargos and binding partners ...

Single-Molecule Assays of Calmodulin Target Binding Detected with a Calmodulin Energy-Transfer Construct

open access: yes, 2016
We have detected single-molecule binding interactions of a target peptide with the calcium-signaling protein calmodulin (CaM) immobilized in an agarose gel, and we have demonstrated the application of a single-molecule binding assay to measure the ...
