Labeling of Bifidobacterium longum Cells with 13C-Substituted Leucine for Quantitative Proteomic Analyses

Stable isotope labeling of amino acids in cell culture was used for Bifidobacterium longum. A comprehensive proteomic strategy was developed and validated by designing an appropriate semidefined medium that allows stable replacement of natural leucine by [13C6]leucine. Using this strategy, proteins...

Sumario:Stable isotope labeling of amino acids in cell culture was used for Bifidobacterium longum. A comprehensive proteomic strategy was developed and validated by designing an appropriate semidefined medium that allows stable replacement of natural leucine by [13C6]leucine. Using this strategy, proteins having variations of at least 50% in their expression rates can be quantified with great confidence
