    Stable Isotope Labeled Products for Biomolecular NMR

    An important tool for high-resolution structure determination for NMR spectroscopy is the use of stable isotopically labeled biomolecules. By either selectively or uniformly incorporating stable isotopes into proteins, the user is able to significantly reduce the complexity of their spectra. 13C, ...

    Stable Labeled Minimal Media and Minimal Media Components for Biomolecular NMR

    The use of E.coli in the expression of isotopically enriched recombinant proteins for NMR studies has remained the most popular technique to date. The prevalence of this method is due to the availability of minimal media as the source of the isotopic label(s). Minimal media has been and continues t...
