    Isolation of Microglia and Analysis of Protein Expression by Flow Cytometry: Avoiding the Pitfall of Microglia Background Autofluorescence
    Authors:  Jeremy C. Burns, Richard M. Ransohoff and Michaël Mingueneau, date: 07/20/2021, view: 819, Q&A: 0
    [Abstract]

    Microglia are a unique type of tissue-resident innate immune cell found within the brain, spinal cord, and retina. In the healthy nervous system, their main functions are to defend the tissue against infectious microbes, support neuronal networks through synapse remodeling, and clear extracellular debris and dying cells through phagocytosis. Many

    Sex-specific Separation of Plasmodium falciparum Gametocyte Populations
    Authors:  Melanie C. Ridgway, Daniela Cihalova and Alexander G. Maier, date: 06/05/2021, view: 1079, Q&A: 0
    [Abstract]

    Plasmodium falciparum is a unicellular eukaryotic parasite that causes malaria in humans. The parasite is spread by Anopheles mosquitoes after ingestion of sexual stage parasites known as gametocytes. Malaria transmission depends on parasites switching from the disease-causing asexual blood forms to male and female gametocytes. The current

    FACS Enrichment of Total Interstitial Cells and Fibroblasts from Adult Mouse Ventricles
    Authors:  Nona Farbehi, Vaibhao Janbandhu, Robert E. Nordon and Richard P. Harvey, date: 05/20/2021, view: 1203, Q&A: 0
    [Abstract]

    Besides cardiomyocytes, the heart contains numerous interstitial cell types, including cardiac fibroblasts, endothelial cells, immune (myeloid and lymphoid) cells, and mural cells (pericytes and vascular smooth muscle cells), which play key roles in heart repair, regeneration, and disease. We recently published a comprehensive map of cardiac

    Assay for Assessing Mucin Binding to Bacteria and Bacterial Proteins
    [Abstract]

    Legionella pneumophila, a Gram-negative bacterium and the causative agent of Legionnaires’ disease, exports over 300 effector proteins/virulence factors, through its type II (T2SS) and type IV secretion systems (T4SS). One such T2SS virulence factor, ChiA, not only functions as a chitinase, but also as a novel mucinase, which we believe aids

    A Simple Microplate Assay for Reactive Oxygen Species Generation and Rapid Cellular Protein Normalization
    Authors:  Neville S. Ng and Lezanne Ooi, date: 01/05/2021, view: 2305, Q&A: 0
    [Abstract] 2',7'-dichlorofluorescein (DCF) and derivatives are commonly used as fluorescent indicators of a broad spectrum of reactive oxygen species (ROS) generation in cell-based assays. However, there are numerous challenges inherent to the utilization of DCF probes for intracellular microscopic analysis, including bleaching and probe efflux. Plate ...
    RNA ImmunoGenic Assay: A Method to Detect Immunogenicity of in vitro Transcribed mRNA in Human Whole Blood
    [Abstract] The mRNA therapeutics is a new class of medicine to treat many various diseases. However, in vitro transcribed (IVT) mRNA triggers immune responses due to recognition by human endosomal and cytoplasmic RNA sensors, but incorporation of modified nucleosides have been shown to reduce such responses. Therefore, an assay signifying important ...
    Quantitative Kinetic Analyses of Histone Turnover Using Imaging and Flow Cytometry
    Authors:  Hanae Sato, Robert H. Singer and John M. Greally, date: 09/05/2020, view: 1832, Q&A: 0
    [Abstract] Dynamic histone changes occur as a central part of chromatin regulation. Deposition of histone variants and post-translational modifications of histones are strongly associated with properties of chromatin status. Characterizing the kinetics of histone variants allows important insights into transcription regulation, chromatin maintenance and ...
    Multiplication and Growth Inhibition Activity Assays for the Zoonotic Malaria Parasite, Plasmodium knowlesi
    Authors:  Franziska Mohring, Thomas A. Rawlinson, Simon J. Draper and Robert W. Moon, date: 09/05/2020, view: 2468, Q&A: 0
    [Abstract] Malaria remains a major cause of morbidity and mortality globally. Clinical symptoms of the disease arise from the growth and multiplication of Plasmodium parasites within the blood of the host. Thus in vitro assays to determine how drug, antibody and genetic perturbations affect the growth rate of Plasmodium parasites ...
    Flow Cytometry of CD14, VDR, Cyp27 and Cyp24 and TLR4 in U937 Cells
    [Abstract] Chronic Kidney Disease (CKD) patients present a micro inflammation state due to failure renal function. The calcitriol has been described as an anti-inflammatory factor that might modulates the inflammatory response in CKD patients. However, these patients have deficiency of Calcitriol due to failure renal function. But, synthesis of this vitamin ...
    A Quantitative Single-cell Flow Cytometry Assay for Retrograde Membrane Trafficking Using Engineered Cholera Toxin
    Authors:  Mariska S. Simpson, Wayne I. Lencer and Phi Luong, date: 08/05/2020, view: 1871, Q&A: 0
    [Abstract] The organization and distribution of proteins, lipids, and nucleic acids in eukaryotic cells is an essential process for cell function. Retrograde trafficking from the plasma membrane to the Golgi and endoplasmic reticulum can greatly modify cell membrane composition and intracellular protein dynamics, and thus typifies a key sorting step. ...
