    Combining Gel Retardation and Footprinting to Determine Protein-DNA Interactions of Specific and/or Less Stable Complexes
    Authors:  Meng-Lun Hsieh, Alice Boulanger, Leslie G. Knipling and Deborah M. Hinton, date: 12/05/2020, view: 1582, Q&A: 0
    [Abstract]

    DNA footprinting is a classic technique to investigate protein-DNA interactions. However, traditional footprinting protocols can be unsuccessful or difficult to interpret if the binding of the protein to the DNA is weak, the protein has a fast off-rate, or if several different protein-DNA complexes are formed. Our protocol differs from traditional

    Structural Analysis of Bordetella pertussis Biofilms by Confocal Laser Scanning Microscopy
    Authors:  Natalia Cattelan, Osvaldo Miguel Yantorno and Rajendar Deora, date: 08/05/2018, view: 5042, Q&A: 0
    [Abstract] Biofilms are sessile communities of microbial cells embedded in a self-produced or host-derived exopolymeric matrix. Biofilms can both be beneficial or detrimental depending on the surface. Compared to their planktonic counterparts, biofilm cells display enhanced resistance to killing by environmental threats, chemicals, antimicrobials and host ...
    Separation and Detection of Phosphorylated and Nonphosphorylated BvgA, a Bordetella pertussis Response Regulator, in vivo and in vitro
    Authors:  Qing Chen, Alice Boulanger, Deborah M. Hinton and Scott Stibitz, date: 11/20/2013, view: 10212, Q&A: 0
    [Abstract] Protein phosphorylation plays a central role in signal transduction in bacteria. However, separation and detection of the phosphorylated protein from its nonphosphorylated form remain challenging. Here we describe a method to detect phosphorylation of the Bordetella pertussis response regulator BvgA, which is phosphorylated at an ...
