Protein labeling in Escherichia coli with 2H, 13C and 15N



Zvi Kelman, Prasad T. Reddy


A number of structural biology techniques such as nuclear magnetic resonance (NMR) and small-angle neutron scattering (SANS) can be performed with proteins with nuclei at natural isotope abundance. However, the use of proteins labeled with heavy isotopes (2H, 13C and 15N) enabled greater measurements flexibility. In this chapter several methods for uniform and fractional protein labeling with heavy isotopes using Escherichia coli in a defined media are described. The methods described can be used for labeling with single or multiple isotopes.
