    Analyzing (Re)Capping of mRNA Using Transcript Specific 5' End Sequencing
    Authors:  Daniel del Valle Morales and Daniel R. Schoenberg, date: 10/20/2020, view: 374, Q&A: 0
    [Abstract] The 5′ cap is a ubiquitous feature of eukaryotic mRNAs. It is added in the nucleus onto newly synthesized pre-mRNA, and in the cytoplasm onto mRNAs after decapping or endonuclease cleavage. Cytoplasmic recapping can occur after loss of the cap at the native 5′ end, or downstream within the body of the mRNA. The identification and location of ...
    Isolation and Transcriptomic Profiling of Single Myofibers from Mice
    [Abstract] Skeletal muscle is composed of different cells and myofiber types, with distinct metabolic and structural features. Generally, transcriptomic analysis of skeletal muscle is performed using whole muscle, resulting in average information as all cells composing the organ contribute to the expression value detected for each gene with the loss of ...
    Yeast Single-cell RNA-seq, Cell by Cell and Step by Step
    [Abstract] Single-cell RNA-seq (scRNA-seq) has become an established method for uncovering the intrinsic complexity within populations. Even within seemingly homogenous populations of isogenic yeast cells, there is a high degree of heterogeneity that originates from a compact and pervasively transcribed genome. Research with microorganisms such as yeast ...
    Adapting the Smart-seq2 Protocol for Robust Single Worm RNA-seq
    [Abstract] Most nematodes are small worms that lack enough RNA for regular RNA-seq protocols without pooling hundred to thousand of individuals. We have adapted the Smart-seq2 protocol in order to sequence the transcriptome of an individual worm. While developed for individual Steinernema carpocapsae and Caenorhabditis elegans larvae as ...
    RNA Capping by Transcription Initiation with Non-canonical Initiating Nucleotides (NCINs): Determination of Relative Efficiencies of Transcription Initiation with NCINs and NTPs
    Authors:  Jeremy G. Bird, Bryce E. Nickels and Richard H. Ebright, date: 06/20/2017, view: 5892, Q&A: 0
    [Abstract] It recently has been established that adenine-containing cofactors, including nicotinamide adenine dinucleotide (NAD+), reduced nicotinamide adenine dinucleotide (NADH), and 3’-desphospho-coenzyme A (dpCoA), can serve as ‘non-canonical initiating nucleotides’ (NCINs) for transcription initiation by bacterial and eukaryotic cellular RNA ...
    Single-molecule RNA Fluorescence in situ Hybridization (smFISH) in Caenorhabditis elegans
    [Abstract] Single-molecule RNA fluorescence in situ hybridization (smFISH) is a technique to visualize individual RNA molecules using multiple fluorescently-labeled oligonucleotide probes specific to the target RNA (Raj et al., 2008; Lee et al., 2016a). We adapted this technique to visualize RNAs in the C. elegans whole ...
    Single-cell Visualization of Chromosome Transcriptional Territories by RNA-paint
    Authors:  Céline Vallot and Claire Rougeulle, date: 09/05/2016, view: 6521, Q&A: 0
    [Abstract] We developed a FISH-based method to directly assess chromosome-wide transcriptional activity, thereby enabling the visualization of the actively transcribed fraction of a chromosome at the single-cell level. We applied this method to probe the activity of X-chromosomes and its instability in the context of human embryonic stem cells and cancer ...
    In vitro Transcription (IVT) and tRNA Binding Assay
    Author:  Sonja MK Schoenfelder, date: 09/20/2014, view: 10925, Q&A: 0
    [Abstract] This protocol describes the coupling of (i) “live” in vitro RNA transcription with (ii) binding by a radiolabeled, pre-formed tRNA followed by native gel electrophoresis and phosphorimager scan to visualize the complex. The necessity arose from the stable structure that one RNA forms in the absence of its interaction partner. The T-box ...
    Single-cell Gene Expression Profiling of Mouse Stem Cells With Fluidigm BiomarkTM Dynamic Array
    Author:  Ana Sevilla, date: 05/05/2013, view: 15359, Q&A: 3
    [Abstract] This protocol describes how to use Fluidigm BiomarkTM 96.96 dynamic arrays for high-throughput expression profiling from single mouse stem cells, assaying up to 96 independent samples with up to 96 quantitative PCR (qPCR) probes (equivalent to 9,216 reactions) in a single experiment. This Dynamic Array contains a network of microfluidic ...
    Isolation of Epithelial Cells from Mouse Gastrointestinal Tract for Western Blot or RNA Analysis
    Authors:  Maged Zeineldin and Kristi Neufeld, date: 11/20/2012, view: 17237, Q&A: 1
    [Abstract] The gastrointestinal (GI) tract is lined by a single layer of epithelial cells which function in secretion, absorption, and digestion. In addition, most GI tract tumors develop from epithelial cells (carcinomas). This protocol describes isolation of the surface epithelium from the underlying stroma, muscular layer and submucosa in the GI tract. In ...
