    Probing the molecular interactions of viral-host protein complexes to understand pathogenicity is essential in modern virology to help the development of antiviral therapies. Common binding assays, such as co-immunoprecipitation or pull-downs, are helpful in investigating intricate viral-host proteins interactions. However, such assays may miss

    Authors:  Vamseedhar Rayaprolu, Shannon Kruse, Ravi Kant, Navid Movahed, Dewey Brooke and Brian Bothner, date: 08/05/2014, view: 11209, Q&A: 1
    [Abstract] Differential Scanning Fluorimetry (DSF) is a rapid, economical, and a straightforward technique for estimating the thermal stability of proteins. The principle involves the binding of a fluorescent dye to thermally exposed hydrophobic pockets of a protein. The dyes used in this technique are highly fluorescent in a non-polar environment and are ...
    Helicase Assays
    Authors:  Xin Wang, Jing Li, Jason Diaz and Jianxin You, date: 03/20/2014, view: 12923, Q&A: 0
    [Abstract] Helicases are a class of enzymes which are motor proteins using energy derived from ATP hydrolysis to move directionally along a nucliec acid phosphodiester backbone (such as DNA, RNA and DNA-RNA hybrids) and separate two annealed nucleic acid strands. Many cellular processes, such as transcription, DNA replication, recombination and DNA repair ...
    Biochemical Assays for MTase Activity
    Authors:  Yu Chen and Deyin Guo, date: 01/20/2014, view: 8472, Q&A: 0
    [Abstract] Methyltransferase (MTase) transfers a methyl group (-CH3) from the donor S-adenosyl-L-methionine (AdoMet or SAM) to biologically active molecules such as hormones, neurotransmitters, lipids, proteins and nucleic acids. The addition of a methyl group causes a change in the physicochemical properties of the molecules. The mRNA cap structure is ...
