    Simplified Epigenome Profiling Using Antibody-tethered Tagmentation
    Authors:  Steven Henikoff, Jorja G. Henikoff and Kami Ahmad, date: 06/05/2021, view: 396, Q&A: 0

    We previously introduced Cleavage Under Targets & Tagmentation (CUT&Tag), an epigenomic profiling method in which antibody tethering of the Tn5 transposase to a chromatin epitope of interest maps specific chromatin features in small samples

    Surface Engineering and Multimodal Imaging of Multistage Delivery Vectors in Metastatic Breast Cancer
    Authors:  Shreya Goel, Mauro Ferrari and Haifa Shen, date: 05/20/2021, view: 941, Q&A: 0

    The design of effective nanoformulations that target metastatic breast cancers is challenging due to a lack of competent imaging and image analysis protocols that can capture the interactions between the injected nanoparticles and metastatic

    A New Method for Studying RNA-binding Proteins on Specific RNAs
    Authors:  Weiping Sun, Ziheng Zhang, Ji-Long Liu and Min Zhuang, date: 05/20/2021, view: 1414, Q&A: 0

    Proximity-based protein labeling has been developed to identify protein-nucleic acid interactions. We have reported a novel method termed CRUIS (CRISPR-based RNA-United Interacting System), which captures RNA-protein interactions in living cells by

    Identification of R-loop-forming Sequences in Drosophila melanogaster Embryos and Tissue Culture Cells Using DRIP-seq
    Authors:  Célia Alecki and Nicole J. Francis, date: 05/05/2021, view: 726, Q&A: 0

    R-loops are non-canonical nucleic structures composed of an RNA–DNA hybrid and a displaced ssDNA. Originally identified as a source of genomic instability, R-loops have been shown over the last decade to be involved in the targeting of
