Experimental Data

Contains experimentally-derived protein half-life data obtained using stable isotope labeling by amino acids (SILAC) coupled with mass spectrometry. This section also contains protein abundance data for both untreated and treated cells obtained from over 20 studies. These data have been normalized and converted to a common unit of molecules per cell.
