    VirScan: High-throughput Profiling of Antiviral Antibody Epitopes
    Authors:  Ellen L. Shrock, Christine L. Shrock and Stephen J. Elledge, date: 07/05/2022, view: 33, Q&A: 0

    Profiling the specificities of antibodies can reveal a wealth of information about humoral immune responses and the antigens they target. Here, we present a protocol for VirScan, an application of the phage immunoprecipitation sequencing (PhIP-Seq)

    HaloChIP-seq for Antibody-Independent Mapping of Mouse Transcription Factor Cistromes in vivo

    Chromatin immunoprecipitation (ChIP) maps, on a genome-wide scale, transcription factor binding sites, and the distribution of other chromatin-associated proteins and their modifications. As such, it provides valuable insights into mechanisms of

    Experimental Models for Cold Exposure of Muscle in vitro and in vivo

    Work in cold environments may have a significant impact on occupational health. In these and similar situations, cold exposure localized to the extremities may reduce the temperature of underlying tissues. To investigate the molecular effects of

    ATAC-Seq of a Single Myofiber from Mus musculus
    Authors:  Korin Sahinyan, Darren M. Blackburn and Vahab D. Soleimani, date: 06/20/2022, view: 1225, Q&A: 0

    Chromatin accessibility is a key determinant of gene expression that can be altered under different physiological and disease conditions. Skeletal muscle is made up of myofibers that are highly plastic and adaptive. Therefore, assessing the

    A Modified Fluctuation Assay with a CAN1 Reporter in Yeast
    Authors:  Pengyao Jiang, Anja R. Ollodart and Maitreya J. Dunham, date: 06/05/2022, view: 524, Q&A: 0

    Understanding the generation of mutations is fundamental to understanding evolution and genetic disease; however, the rarity of such events makes experimentally identifying them difficult. Mutation accumulation (MA) methods have been widely used. MA

    A Highly Sensitive Method to Efficiently Profile the Histone Modifications of FFPE Samples
    Authors:  Linxuan Zhao, Vamsi Krishna Polavarapu, Ram Prakash Yadav, Pengwei Xing and Xingqi Chen, date: 05/20/2022, view: 758, Q&A: 0

    The majority of biopsies in both basic research and translational cancer studies are preserved in the format of archived formalin-fixed paraffin-embedded (FFPE) samples. Profiling histone modifications in archived FFPE tissues is critically

    Purification of Mitochondrial Ribosomal Complexes from Trypanosoma cruzi and Leishmania tarentolae for Cryo-EM Analysis
    Authors:  Stéphanie Durrieu-Gaillard, Marie Sissler and Yaser Hashem, date: 05/20/2022, view: 916, Q&A: 1

    Kinetoplastids are unicellular eukaryotic parasites responsible for human pathologies such as Chagas disease, sleeping sickness or Leishmaniasis, caused by Trypanosoma cruzi, Trypanosoma brucei, and various Leishmania spp., respectively. They harbor

    A Molecular Cloning and Sanger Sequencing-based Protocol for Detecting Site-specific DNA Methylation
    Authors:  Wei Guo, Anthony Cannon and Damon Lisch, date: 05/05/2022, view: 691, Q&A: 1

    DNA methylation is a conserved chemical modification, by which methyl groups are added to the cytosine of DNA molecules. Methylation can influence gene expression without changing the sequence of a particular gene. This epigenetic effect is an

    An Improved EMSA-based Method to Prioritize Candidate cis-REs for Further Functional Validation
    Authors:  Ting Wu and Gang Li, date: 04/20/2022, view: 588, Q&A: 0

    Cells are the complex product of gene expression programs that involve the coordinated transcription of thousands of genes controlled by cis-regulatory elements (cis-REs). Therefore, identification of cis-REs is the key to decipher the mechanisms

    circFL-seq, A Full-length circRNA Sequencing Method
    Authors:  Zelin Liu and Ence Yang, date: 04/20/2022, view: 986, Q&A: 1

    Due to overlapping sequences with linear cognates, identifying internal sequences of circular RNA (circRNA) remains a challenge. Recently, we have developed a full-length circRNA sequencing method (circFL-seq) and computational pipeline, to profile
