Molecular Basis for Actin Polymerization Kinetics Modulated by Solution Crowding

open access: yesBiomolecules, 2023
Actin polymerization drives cell movement and provides cells with structural integrity. Intracellular environments contain high concentrations of solutes, including organic compounds, macromolecules, and proteins.

Dynamics of cell membrane lesions and adaptive conductance under the electrical stress

open access: yesCell Stress
Exceeding physiological limits of the cell membrane potential compromises structural integrity, enabling the passage of normally impermeant solutes and disrupting cell function.

Single molecule turnover of fluorescent ATP by myosin and actomyosin unveil elusive enzymatic mechanisms

open access: yesCommunications Biology, 2021
With fluorescence based-TIRF microspectroscopy, Ušaj et al. unveil mechanistic details about the ATP turnover rates by myosin and actomyosin with enzymatic reaction pathways that were not possible to obtain from ensemble studies.

Imaging Microtubules in vitro at High Resolution while Preserving their Structure

open access: yesBio-Protocol, 2021
Microtubules (MT) are the most rigid component of the cytoskeleton. Nevertheless, they often appear highly curved in the cellular context and the mechanisms governing their overall shape are poorly understood.

Improved field uniformity with shadowless TIRF excitation.

open access: yes, 2015
(A, B) Images (500x300 pixel, 40 x 24 μm) of rhodamine film on a coverglass. The image in A was captured using stationary-spot (conventional) TIRF excitation at 488 nm; that in B shows the same specimen but imaged by spinning-spot TIRF excitation.

Flat-top TIRF illumination boosts DNA-PAINT imaging and quantification

open access: yesNature Communications, 2019
The use of TIRF microscopy for DNA-PAINT experiments is limited by inhomogeneous illumination. Here the authors show that quantitative analysis of single-molecule TIRF experiments can be improved by using a segment-wise analysis approach and overcome by ...

Total Internal Reflection Fluorescence (TIRF) Microscopy [PDF]

open access: yesCurrent Protocols in Cytometry, 2009
AbstractTotal internal reflection fluorescence (TIRF) microscopy (TIRFM) is an elegant optical technique that provides for the excitation of fluorophores in an extremely thin axial region (“optical section”). The method is based on the principle that when excitation light is totally internally reflected in a transparent solid (e.g., coverglass) at its ...

Minimal design inverted TIRF microscope.

open access: yes, 2013
a) A photograph of the instrument, the view on the objective is hidden by the x-y sample stage. The inset cartoon shows the open-top sample chamber. b) A cross-sectional drawing of the essential components of the instrument. The TIRF objective is mounted
