    Measuring Cell Growth and Junction Development in Epithelial Cells Using Electric Cell-Substrate Impedance Sensing (ECIS)
    Authors:  Shaista Anwer and Katalin Szaszi, date: 08/20/2020, view: 2399, Q&A: 0
    [Abstract] Electric Cell-substrate Impedance Sensing (ECIS) is an automated method that can be used to quantify processes such as cell attachment, growth, migration and barrier functions (i.e., the properties of tight junctions). The method provides simultaneous information on cell number and tight junction function by detecting electric parameters ...
    Imaging VIPER-labeled Cellular Proteins by Correlative Light and Electron Microscopy
    [Abstract] Advances in fluorescence microscopy (FM), electron microscopy (EM), and correlative light and EM (CLEM) offer unprecedented opportunities for studying diverse proteins and nanostructures involved in fundamental cell biology. It is now possible to visualize and quantify the spatial organization of cellular proteins and other macromolecules by FM, ...
    Implementing VIPER for Imaging Cellular Proteins by Fluorescence Microscopy
    Authors:  Julia K. Doh, Caroline A. Enns and Kimberly E. Beatty, date: 11/05/2019, view: 2902, Q&A: 0
    [Abstract] Genetically-encoded tags are useful tools for multicolor and multi-scale cellular imaging. Versatile Interacting Peptide (VIP) tags, such as VIPER, are new genetically-encoded tags that can be used in various imaging applications. VIP tags consist of a coiled-coil heterodimer, with one peptide serving as the genetic tag and the other (“probe ...
    Generation of CoilR Probe Peptides for VIPER-labeling of Cellular Proteins
    Authors:  Julia K. Doh, Savannah J. Tobin and Kimberly E. Beatty, date: 11/05/2019, view: 2797, Q&A: 0
    [Abstract] Versatile Interacting Peptide (VIP) tags are a new class of genetically-encoded tag designed for imaging cellular proteins by fluorescence and electron microscopy. In 2018, we reported the VIPER tag (Doh et al., 2018), which contains two elements: a genetically-encoded peptide tag (i.e., CoilE) and a probe peptide (i.e., ...
    Propidium Iodide Staining of Cells for FACS Analysis
    Author:  Hui Zhu, date: 06/05/2012, view: 51995, Q&A: 2
    [Abstract] Fluorescence Activated Cell Sorting (FACS) is used to study DNA cell content. Propidium iodide (PI) intercalates into double-stranded nucleic acids and fluoresces. It is excluded by viable cells but can penetrate cell membranes of dying or dead cells. Thus PI staining is included in immunofluorescent staining protocols to identify dead cells. DNA ...
