    Localizing Genome Segments and Protein Products of a Multipartite Virus in Host Plant Cells
    Authors:  Marie-Stephanie Vernerey, Elodie Pirolles, Stephane Blanc and Anne Sicard, date: 12/05/2019, view: 94, Q&A: 0
    [Abstract] A founding paradigm in virology is that the spatial unit of the viral replication cycle is an individual cell. This concept applied to multipartite viruses–which have a genome composed of two or more nucleic acid segments, each individually encapsulated–implies that all segments constituting a viral genome need to coinfect the same host cell for ...
    Enhanced-ice-COLD-PCR for the Sensitive Detection of Rare DNA Methylation Patterns in Liquid Biopsies
    Authors:  Florence Mauger and Jörg Tost, date: 12/05/2019, view: 66, Q&A: 0
    [Abstract] In the context of precision medicine, the identification of novel biomarkers for the diagnosis of disease, prognosis, predicting treatment outcome and monitoring of treatment success is of great importance. The analysis of methylated circulating-cell free DNA provides great promise to complement or replace genetic markers for these applications, ...
    DNase I Chromatin Accessibility Analysis
    Authors:  Brook S. Nepon-Sixt and Mark G. Alexandrow, date: 12/05/2019, view: 78, Q&A: 0
    [Abstract] Chromatin consists of compacted DNA in complex with proteins and contributes to the organization of DNA and its stability. Furthermore, chromatin plays key roles in regulating cellular processes such as DNA replication, transcription, DNA repair, and mitosis. Chromatin assumes more compact (inaccessible) or decondensed (accessible) conformations ...
    Determination of Chromatin Accessibility in Drosophila Midgut Enterocytes by in situ 5mC Labeling
    Authors:  Eliya Bitman-Lotan, Hector Rincon-Arano, Gal Raz and Amir Orian, date: 11/20/2019, view: 234, Q&A: 0
    [Abstract] Regulation of gene expression involves dynamic changes in chromatin organization, where in many cases open chromatin structure correlates with gene activation. Several methods enable monitoring changes in chromatin accessibility, including ATAC-seq, FAIRE-seq, MNase-seq and DNAse-seq methods, which involve Next-generation-sequencing (NGS). ...
    Quantification of HIV-2 DNA in Whole Blood
    Authors:  Zsófia Szojka, Sara Karlson, Marianne Jansson and Patrik Medstrand, date: 10/20/2019, view: 378, Q&A: 0
    [Abstract] Time to AIDS infection is longer with HIV-2, compared to HIV-1, but without antiretroviral therapy both infections will cause AIDS-related mortality. In HIV-2 infection, monitoring of antiretroviral treatment (ART) efficacy is challenging since a large proportion of HIV-2-infected individuals displays low or undetectable plasma RNA levels. Hence, ...
    Simple Synthesis of Functionalized Paramagnetic Beads for Nucleic Acid Purification and Manipulation
    [Abstract] The purification of nucleic acids is one of the most common procedures employed in modern molecular biology laboratories. Typically, commercial column-based protocols are utilized to isolate DNA or RNA from various sources. However, these methods not only require specialized equipment, but are also extremely expensive for high-throughput ...
    ATAC-seq on Sorted Adult Mouse Neurons
    Authors:  Erin A. Clark, Yasuyuki Shima and Sacha Nelson, date: 10/05/2019, view: 534, Q&A: 0
    [Abstract] Transcription regulation is a key aspect of cellular identity established during development and maintained into adulthood. Molecular and biochemical assays that probe the genome are critical tools in exploring mechanisms of transcription regulation and cell type identity. The mammalian brain is composed of a huge diversity of cell types with ...
    In situ Hybridization of Plant-parasitic Nematode Globodera pallida Juveniles to Detect Gene Expression
    [Abstract] In this study, we describe a standard whole mount in situ hybridization method which is used to determine the spatial-temporal expression pattern of genes from Globodera spp. Unlike more invasive radioactive labeling approaches, this technique is based on a safe, highly specific enzyme-linked immunoassay where a Digoxigenin ...
    Using indCAPS to Detect CRISPR/Cas9 Induced Mutations
    Authors:  Charles Hodgens, Zachary L. Nimchuk and Joseph J. Kieber, date: 09/20/2019, view: 300, Q&A: 0
    [Abstract] Cleaved amplified polymorphic sequences (CAPS) assays are useful tools for detecting small mutations such as single nucleotide polymorphisms (SNPs) or insertion/deletions (indels) present in an amplified DNA fragment. A mutation that disrupts or creates a restriction site will prevent cleavage by a restriction enzyme, allowing discrimination of ...
    A Refined Protocol for Identifying Citrulline-specific Monoclonal Antibodies from Single Human B Cells from Rheumatoid Arthritis Patient Material
    [Abstract] We describe here a detailed, refined protocol for the generation of citrulline-specific monoclonal antibodies from single human B cells from rheumatoid arthritis (RA) patients. This protocol provides a detailed guide of the procedure starting from single B cells of your choice and followed by amplification of the variable region of immunoglobulin ...
