    Intracellular IRF5 Dimerization Assay
    Authors:  Cherrie D. Sherman and Betsy J. Barnes, date: 05/20/2021, view: 1019, Q&A: 0

    The intracellular interferon regulatory factor 5 (IRF5) dimerization assay is a technique designed to measure molecular interaction(s) with endogenous IRF5. Here, we present two methods that detect endogenous IRF5 homodimerization and interaction of

    Native Co-immunoprecipitation Assay to Identify Interacting Partners of Chromatin-associated Proteins in Mammalian Cells
    Authors:  Afzal Husain, Nasim A. Begum, Maki Kobayashi and Tasuku Honjo, date: 12/05/2020, view: 1959, Q&A: 0

    Protein-protein interactions play key roles in nuclear processes including transcription, replication, DNA damage repair, and recombination. Co-immunoprecipitation (Co-IP) followed by western blot or mass spectrometry is an invaluable approach to

    Measurement of Protein-Protein Interactions through Microscale Thermophoresis (MST)
    Authors:  Magnez Romain, Bryan Thiroux, Morgane Tardy, Bruno Quesnel and Xavier Thuru, date: 04/05/2020, view: 2619, Q&A: 0
    The binding interactions of PD-1 and PD-L1 have been studied by surface plasmon resonance (SPR) and isothermal titration calorimetry (ITC) over the past few years, but these investigations resulted in controversy regarding the values of the ...
    Assessing Self-interaction of Mammalian Nuclear Proteins by Co-immunoprecipitation
    Authors:  Claudia Cattoglio, Iryna Pustova, Xavier Darzacq, Robert Tjian and Anders S. Hansen, date: 02/20/2020, view: 3575, Q&A: 0
    Protein-protein interactions constitute the molecular foundations of virtually all biological processes. Co-immunoprecipitation (CoIP) experiments are probably the most widely used method to probe both heterotypic and homotypic protein-protein ...
    Proximity Ligation Assay for the Investigation of the Intramolecular Interaction of ELMO1
    Authors:  Wai Wa Ray Chan, Dik Long Dennis Chau, Wen Li and Kwok-Fai Lau, date: 12/05/2019, view: 2355, Q&A: 0
    Intramolecular interaction is a common mechanism that regulates protein activities. Conventionally, such interactions are investigated by classical in vitro biochemical assays. Here, we describe a protocol for studying the intramolecular ...
    Detection of in vivo Protein Interactions in All Bacterial Compartments by Förster Resonance Energy Transfer with the Superfolder mTurquoise2 ox-mNeongreen FRET Pair
    Authors:  Nils Y. Meiresonne, Elisa Consoli, Laureen M.Y. Mertens and Tanneke den Blaauwen, date: 12/05/2019, view: 3328, Q&A: 0
    This protocol was developed to qualitatively and quantitatively detect protein-protein interactions in all compartments of Escherichia coli by Förster Resonance Energy Transfer (FRET) using the Superfolder mTurquoise2 ox-mNeonGreen FRET ...
    Measuring Small-molecule Inhibition of Protein Interactions in Live Cells Using FLIM-FRET
    Authors:  James M. Pemberton, Qian Liu and David W. Andrews, date: 10/20/2019, view: 3723, Q&A: 0
    This protocol was designed to quantitatively measure small-molecule displacement of proteins in live mammalian cells using fluorescence lifetime imaging microscopy–Förster resonance energy transfer (FLIM-FRET). Tumour cell survival is often ...
    An in vitro Microscopy-based Assay for Microtubule-binding and Microtubule-crosslinking by Budding Yeast Microtubule-associated Protein
    Authors:  Yili Zhu, Weimin Tan and Wei-Lih Lee, date: 12/05/2018, view: 4162, Q&A: 0
    In this protocol, we describe a simple microscopy-based method to assess the interaction of a microtubule-associated protein (MAP) with microtubules. The interaction between MAP and microtubules is typically assessed by a co-sedimentation assay, ...
    FRET-based Stoichiometry Measurements of Protein Complexes in vitro
    Authors:  Francesca Mattiroli, Yajie Gu and Karolin Luger, date: 02/05/2018, view: 6390, Q&A: 0
    For a complete understanding of biochemical reactions, information on complex stoichiometry is essential. However, measuring stoichiometry is experimentally challenging. Our lab has developed a FRET-based assay to study protein complex stoichiometry ...
    Detection of Protein Interactions in the Cytoplasm and Periplasm of Escherichia coli by Förster Resonance Energy Transfer
    Authors:  Nils Y. Meiresonne, Svetlana Alexeeva, René van der Ploeg and Tanneke den Blaauwen, date: 01/20/2018, view: 7469, Q&A: 0
    This protocol was developed to qualitatively and quantitatively detect protein-protein interactions in Escherichia coli by Förster Resonance Energy Transfer (FRET). The described assay allows for the previously impossible in vivo ...
