QUANTITATIVE CONFOCAL LASER SCANNING MICROSCOPY

open access: yesImage Analysis and Stereology, 2011
This paper discusses recent advances in confocal laser scanning microscopy (CLSM) for imaging of 3D structure as well as quantitative characterization of biomolecular interactions and diffusion behaviour by means of one- and two-photon excitation.

Protein Mobility in the Cytoplasm of Escherichia coli [PDF]

open access: yes, 1999
The rate of protein diffusion in bacterial cytoplasm may constrain a variety of cellular functions and limit the rates of many biochemical reactions in vivo. In this paper, we report noninvasive measurements of the apparent diffusion coefficient of green

Live-Cell Imaging of Single Receptor Composition Using Zero-Mode Waveguide Nanostructures [PDF]

open access: yes, 2012
We exploit the optical and spatial features of subwavelength nanostructures to examine individual receptors on the plasma membrane of living cells. Receptors were sequestered in portions of the membrane projected into zero-mode waveguides.

Geometrically Tunable Scaffold‐Free Muscle Bioconstructs for Treating Volumetric Muscle Loss

open access: yesAdvanced Healthcare Materials, EarlyView.
Volumetric muscle loss is associated with traumatic muscle resulting in permanent functional impairment. Mold‐based, scaffold‐free, high‐density muscle tissue bioconstructs are developed in customizable geometric shapes and sizes. The transplanted rectangular solid‐shaped muscle bioconstructs improved muscle force recovery and tissue regeneration in ...

Controlling Intestinal Organoid Polarity using Synthetic Dynamic Hydrogels Decorated with Laminin‐Derived IKVAV Peptides

open access: yesAdvanced Healthcare Materials, EarlyView.
Design rules are presented to control intestinal organoid polarity in fully synthetic hydrogels. The laminin‐derived IKVAV sequence is crucial to obtain correct intestinal organoid polarity. Increasing hydrogel dynamics further supports the growth of correctly polarized intestinal organoids, while a bulk level of stiffness (G’ ≈ 0.7 kPa) is crucial to ...

Membrane fluidity is regulated by the C. elegans transmembrane protein FLD-1 and its human homologs TLCD1/2

open access: yeseLife, 2018
Dietary fatty acids are the main building blocks for cell membranes in animals, and mechanisms must therefore exist that compensate for dietary variations. We isolated C.

Time-lapse imaging of Drosophila testis for monitoring actin dynamics and sperm release

open access: yesSTAR Protocols, 2022
Summary: Here we describe a simple step-by-step protocol for collecting high-resolution, time-lapse images of intact Drosophila testis ex vivo for a limited period using a confocal microscope, with minimum photo-toxic damage, to monitor spermatid ...

Structural changes in cartilage and collagen studied by high temperature Raman spectroscopy [PDF]

open access: yes, 2017
Understanding the high temperature behavior of collagen and collagenous tissue is important for surgical procedures and biomaterials processing for the food, pharmaceutical, and cosmetics industries. One primary event for proteins is thermal denaturation
