    Live Confocal Imaging of Brachypodium Spikelet Meristems
    Author:  Devin Lee O'Connor, date: 09/20/2018, view: 52, Q&A: 0
    [Abstract] Live confocal imaging of fluorescent reporters and stains in plant meristems provides valuable measurements of gene expression, protein dynamics, cell polarity, cell division, and growth. The spikelet meristem in the grass Brachypodium distachyon (Brachypodium) is well suited to live imaging because of the ease of dissection, small ...
    Extracting and Integrating Protein Localization Changes from Multiple Image Screens of Yeast Cells
    Authors:  Alex X Lu, Louis-Francois Handfield and Alan M Moses, date: 09/20/2018, view: 47, Q&A: 0
    [Abstract] The evaluation of protein localization changes in cells under diverse chemical and genetic perturbations is now possible due to the increasing quantity of screens that systematically image thousands of proteins in an organism. Integrating information from different screens provides valuable contextual information about the protein function. For ...
    Fabrication and Use of the Dual-Flow-RootChip for the Imaging of Arabidopsis Roots in Asymmetric Microenvironments
    [Abstract] This protocol provides a detailed description of how to fabricate and use the dual-flow-RootChip (dfRootChip), a novel microfluidic platform for investigating root nutrition, root-microbe interactions and signaling and development in controlled asymmetric conditions. The dfRootChip was developed primarily to investigate how plants roots interact ...
    6-hydroxydopamine (6-OHDA) Oxidative Stress Assay for Observing Dopaminergic Neuron Loss in Caenorhabditis elegans
    Authors:  Sarah-Lena Offenburger and Anton Gartner, date: 09/20/2018, view: 27, Q&A: 0
    [Abstract] The nematode Caenorhabditis elegans is a powerful genetic model that can be used to investigate neuronal death. Research using C. elegans has been crucial to characterize cell death programmes that are conserved in mammals. Many neuronal signaling components, such as those mediating dopaminergic neurotransmission, are preserved ...
    Image-Based Analysis of Mitochondrial Area and Counting from Adult Mouse Dopaminergic Neurites
    Authors:  Nadee Nissanka, Carlos T Moraes and Mlena Pinto, date: 08/20/2018, view: 217, Q&A: 0
    [Abstract] Mitochondria form dynamic cytoplasmic networks which undergo morphological changes in order to adapt to cellular stresses and signals. These changes can include alterations in size and number within a given cell. Analysis of the whole network can be a useful metric to assess overall mitochondrial health, particularly in neurons, which are highly ...
    HCV Reporter System (Viral Infection-Activated Split-Intein-Mediated Reporter System) for Testing Virus Cell-to-cell Transmission ex-vivo
    Authors:  Fanfan Zhao, Ting Zhao, Libin Deng, Dawei Lv, Xiaolong Zhang, Xiaoyu Pan, Jun Xu and Gang Long, date: 08/05/2018, view: 374, Q&A: 0
    [Abstract] Hepatitis C virus (HCV) spread involves two distinct entry pathways: cell-free transmission and cell-to-cell transmission. Cell-to-cell transmission is not only an efficient way for viruses to spread but also an effective method for escaping neutralizing antibodies. We adapted the viral infection-activated split-intein-mediated reporter system ...
    Detection of Apoptosis-like Cell Death in Ustilago maydis by Annexin V-FITC Staining
    Authors:  Dibya Mukherjee, Aroni Mitra and Anupama Ghosh, date: 08/05/2018, view: 284, Q&A: 0
    [Abstract] Programmed cell death (PCD) guides the transition between key developmental stages in many organisms. PCD also remains an important fate for many organisms upon exposure to different stress conditions. Therefore, an insight into the progression of PCD during the execution of a biological phenomenon can yield significant details of the underlying ...
    Structural Analysis of Bordetella pertussis Biofilms by Confocal Laser Scanning Microscopy
    Authors:  Natalia Cattelan, Osvaldo Miguel Yantorno and Rajendar Deora, date: 08/05/2018, view: 284, Q&A: 0
    [Abstract] Biofilms are sessile communities of microbial cells embedded in a self-produced or host-derived exopolymeric matrix. Biofilms can both be beneficial or detrimental depending on the surface. Compared to their planktonic counterparts, biofilm cells display enhanced resistance to killing by environmental threats, chemicals, antimicrobials and host ...
    Direct Visualization of the Multicopy Chromosomes in Cyanobacterium Synechococcus elongatus PCC 7942
    Authors:  Ryudo Ohbayashi, Hirofumi Yoshikawa and Satoru Watanabe, date: 08/05/2018, view: 257, Q&A: 0
    [Abstract] Cyanobacteria are prokaryotic organisms that carry out oxygenic photosynthesis. The fresh water cyanobacterium Synechococcus elongatus PCC 7942 is a model organism for the study of photosynthesis and gene regulation, and for biotechnological applications. Besides several freshwater cyanobacteria, S. elongatus 7942 also contains ...
    Fluorophore-Based Mitochondrial Ca2+ Uptake Assay
    Author:  Charles B. Phillips, date: 07/20/2018, view: 252, Q&A: 0
    [Abstract] The physiological importance of mitochondrial calcium uptake, observed in processes such as ATP production, intracellular calcium signaling, and apoptosis, makes desirable a simple, straightforward way of investigating this event with unambiguous results. The following protocol uses a calcium-sensitive, membrane-impermeable fluorophore to monitor ...
