Single-Molecule Anisotropy Imaging [PDF]

open access: yesBiophysical Journal, 1999
A novel method, single-molecule anisotropy imaging, has been employed to simultaneously study lateral and rotational diffusion of fluorescence-labeled lipids on supported phospholipid membranes. In a fluid membrane composed of 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine, in which the rotational diffusion time is on the order of the excited-state ...

Imaging proteins at the single-molecule level [PDF]

open access: yesProceedings of the National Academy of Sciences, 2017
Significance We report a method to image and reveal structural details of proteins on a truly single-molecule level. Low-energy electron holography is used to image individual proteins electrospray deposited on freestanding graphene.

Duplex DNA engagement and RPA oppositely regulate the DNA-unwinding rate of CMG helicase

open access: yesNature Communications, 2020
During eukaryotic chromosome replication cells utilize ring-shaped CMG helicase that separates the two strands of the DNA double helix. Here the authors reveal that CMG helicase activity is inhibited by duplex DNA engagement at the fork, which is ...

Live cell imaging of single RNA molecules with fluorogenic Mango II arrays

open access: yesNature Communications, 2020
Fluorogenic RNA aptamers have been used for RNA imaging, but folding and fluorescence stability often limited their use in high resolution applications.

Generation of versatile ss-dsDNA hybrid substrates for single-molecule analysis

open access: yesSTAR Protocols, 2021
Summary: Here, we describe a rapid and versatile protocol to generate gapped DNA substrates for single-molecule (SM) analysis using optical tweezers via site-specific Cas9 nicking and force-induced melting. We provide examples of single-stranded (ss) DNA

Negative Staining Transmission Electron Microscopy of HIV Viral Particles Permeabilized with PFO and Capsid Stabilized with IP6

open access: yesBio-Protocol, 2022
The human immunodeficiency virus 1 (HIV-1) consists of a viral membrane surrounding the conical capsid. The capsid is a protein container assembled from approximately 1,500 copies of the viral capsid protein (CA), functioning as a reaction and transport ...

Genetic screening for anticancer genes highlights FBLN5 as a synthetic lethal partner of MYC

open access: yesCell Communication and Signaling, 2023
Background When ectopically overexpressed, anticancer genes, such as TRAIL, PAR4 and ORCTL3, specifically destroy tumour cells without harming untransformed cells. Anticancer genes can not only serve as powerful tumour specific therapy tools but studying

SNX9-induced membrane tubulation regulates CD28 cluster stability and signalling

open access: yeseLife, 2022
T cell activation requires engagement of a cognate antigen by the T cell receptor (TCR) and the co-stimulatory signal of CD28. Both TCR and CD28 aggregate into clusters at the plasma membrane of activated T cells.
