    [Abstract] Protein synthesis is one of the most fundamental biological processes to maintain cellular proteostasis. Azidohomoalaine (AHA) is a non-radioactive and “clickable” amino acid analog of methionine which can be incorporated into newly synthesized proteins. Thus, AHA-labeled nascent proteins can be detected and quantified through fluorescent labeling ...

    Authors:  Carole Henique, Olivia Lenoir and Pierre-Louis Tharaux, date: 04/20/2019, view: 228, Q&A: 0
    [Abstract] In glomerular diseases, podocytes are one type of cells involved in dysfunction of glomerular filtration. In these conditions, podocyte proteins expression change. Therefore, immunofluorescent staining of podocytes can be performed to visualize podocyte localization of proteins of interest. In this protocol, we detail a method to stain podocytes ...
    Displaced Object Recognition Memory in Rats
    Authors:  Ali N. Mclagan and Jena B. Hales, date: 04/20/2019, view: 233, Q&A: 0
    [Abstract] The Displaced Object Recognition (DOR) task, sometimes called the Novel Object Location task, assesses spatial recognition memory without navigational demands, explicit instruction, or the need for multiple days of training. This memory task has two phases. First, the subject is familiarized to an open arena with two objects and is allowed to ...

    Authors:  Hua Jiang, Martin S. Taylor, Kelly R. Molloy, Ilya Altukhov and John LaCava, date: 04/05/2019, view: 359, Q&A: 0
    [Abstract] Long Interspersed Nuclear Element-1 (LINE-1, L1) constitutes a family of autonomous, self-replicating genetic elements known as retrotransposons. Although most are inactive, copious L1 sequences populate the human genome. L1s proliferate in a ‘copy-and-paste’ fashion through an RNA intermediate; a full-length L1 transcript is ~6,000 nucleotides ...
    Quantification of Hepatitis B Virus Covalently Closed Circular DNA in Infected Cell Culture Models by Quantitative PCR
    Authors:  Bingqian Qu and Stephan Urban, date: 04/05/2019, view: 347, Q&A: 0
    [Abstract] Persistence of the human hepatitis B virus (HBV) requires the maintenance of covalently closed circular (ccc)DNA, the episomal genome reservoir in nuclei of infected hepatocytes. cccDNA elimination is a major aim in future curative therapies currently under development. In cell culture based in vitro studies, both hybridization- and ...
