4.1.1 Isotopic metabolic labeling
The metabolic isotope labelling technique is based on the use of modified culture media incorporating labelled amino acids in place of native amino acids. As a result, proteins derived from cells grown on these modified culture media incorporate the tagged amino acids in their sequences. As a result, this technique limits its field of application to proteins from cultured cells. Isotope incorporation methodology was first presented in 2002 by Matthias...
