Validation of the intra and inter-individual analysis by western blotting.

The coefficient of variation of four proteins with various dispersion levels was calculated by western blotting. The intra and inter-individual variation analysis based on proteomic quantitative data (n = 3) were compared with that obtained by western blot analysis of the three subjects used for the proteomic analysis and three additional subjects. The table 2 regroups the average of the intra CV and the inter CV calculated from the proteomic results (n = 3) and the CV calculated from the western blot data (n = 6).
