Method	"In an effort to segregate these two underlying mechanisms [protein synthesis and breakdown], a novel multitagging approach was developed based on stable isotope tagging (SILAC) and isobaric tag for relative and absolute quantification (iTRAQ) labelling."
Comments	"Figure 6 shows the distribution of kmultitag values for 115 proteins quantified using SILAC-iTRAQ multitagging approach. The rate constants ranged from about 0.05 h^-1 to over 0.20 h^-1 for some proteins. The median value of kmultitag for the proteins was 0.097 h^-1 while the 25th and 75th percentile values were 0.081 h^-1 and 0.116 h^-1 respectively. This indicates that the majority of the proteins have kmultitag values ranging within a small interval with only a few proteins displaying very high or low rates of degradation. A list of these proteins, their kmultitag values, number of peptide hits and other relevant information are shown in Table 1." See notes beneath table
