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

<p>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 <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0077471#pone-0077471-t002" target="_blank">table 2</a> 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).
