Stable isotope labeling by amino acids in cell culture (SILAC) enables the relative quantification of protein amounts and posttranslational modifications in complex biological samples through the use of stable heavy isotope–labeled amino acids. Here we describe methods for the application of SILAC to fission yeast Schizosaccharomyces pombe using either labeled lysine or a combination of labeled lysine and labeled arginine. The latter approach is more complicated than the use of labeled lysine alone but may yield a more comprehensive (phospho)proteomic analysis. The protocol includes methods for construction of SILAC-compatible strains, growth of cultures in labeled medium, cell harvesting, and protein extraction.
