    Cell Type-specific mRNA Purification in Caenorhabditis elegans via Translating Ribosome Affinity Purification
    Authors:  Ian G. McLachlan and Steven W. Flavell, date: 08/05/2019, view: 269, Q&A: 0
    [Abstract] Cell type-specific molecular profiling is widely used to gain new insights into the diverse cell types that make up complex biological tissues. Translating ribosome affinity purification (TRAP) is a method in which the cell type-specific expression of epitope-tagged ribosomal subunits allows one to purify actively translating mRNAs without the ...
    Optogenetic Inactivation of Transcription Factors in the Early Embryo of Drosophila
    Authors:  Stephen L. McDaniel and Melissa M. Harrison, date: 07/05/2019, view: 601, Q&A: 0
    [Abstract] The early embryo of Drosophila melanogaster exists as a rapidly dividing syncytium of nuclei that are transcriptionally silent. Maternally deposited factors are required to awaken the genome and assist in the transition from maternal to zygotic control of development. Because many of these essential factors are maternally deposited and ...
    Enterovirus Competition Assay to Assess Replication Fitness
    Authors:  Valeria Lulla and Andrew E. Firth, date: 05/20/2019, view: 615, Q&A: 0
    [Abstract] In virology the difference between the fitness of two viruses can be determined by using various methods, such as virus titer, growth curve analysis, measurement of virus infectivity, analysis of produced RNA copies and viral protein production. However, for closely performing viruses, it is often very hard to distinguish the differences. In vitro ...
    Identification of RNase-sensitive LINE-1 Ribonucleoprotein Interactions by Differential Affinity Immobilization
    Authors:  Hua Jiang, Martin S. Taylor, Kelly R. Molloy, Ilya Altukhov and John LaCava, date: 04/05/2019, view: 1101, 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 ...
