[Abstract] This protocol aims to visualize the filamentous actin network in Chlamydomonas reinhardtii. We improved fixed-cell labeling conditions using the F-actin probe, phalloidin. We created a Chlamydomonas-optimized protocol by halving the phalloidin incubation time, electing for optimal fixation conditions, and selecting for a healthy ...
Flow Cytometry Assay for Recycling of LFA-1 in T-lymphocytes
[Abstract] To enable cells to move forward, cell surface integrins are internalized into an endosomal compartment and subsequently intracellularly transported to be re-exposed at a new site on the cell membrane. Leukocytes are the fastest migrating cell type in the human body, which express the leukocyte-specific integrin LFA-1. Here, we describe a flow ...
Relative Quantitation of Polymerized Actin in Suspension Cells by Flow Cytometry
[Abstract] The amount of polymerized actin within a cell can vary widely due to natural processes and/or experimentally induced perturbations. We routinely use this protocol to measure relative polymerized actin content between cell populations by staining cells in suspension with fluorescent phalloidin, then measuring total cell fluorescence using flow ...
Immunogold Electron Microscopy of the Autophagosome Marker LC3
[Abstract] Even though autophagy was firstly observed by transmission electron microscopy already in the 1950s (reviewed in Eskelinen et al., 2011), nowadays this technique remains one of the most powerful systems to monitor autophagic processes. The autophagosome, an LC3-positive double membrane structures enclosing cellular materials, represents ...
