The SILAC-procedure in short:

Cells are grown in culture media that are identical with exception of amino acids. The “light” culture contains all the amino acids in unlabelled form andthe “heavy” culture contains one or two amino acids in labelled form. The labelled amino acids are usually L-Lysine labelled with ²H(D4),¹³C or ¹³C¹⁵N and/or arginine labelled with ¹³C or ¹³C¹⁵N. Thelabelled amino acids increase the molecular weight allowing identification and quantification of the proteins/peptides stemming from culture light and heavy,respectively.
