Abstract

Cell line-based proteomics studies are susceptible to intrinsic biological variation that contributes to increasing false positive claims; most of the methods that follow these changes offer a limited understanding of the biological system. We applied a quantitative proteomic strategy (iTRAQ) to detect intrinsic protein variation across SH-SY5Y cell culture replicates. More than 95% of the quantified proteins presented a coefficient of variation (CV) < 20% between biological replicates and the variable proteins, which included cytoskeleton, cytoplasmic and housekeeping proteins, are widely reported in proteomic studies. We recommend this approach as an additional quality control before starting any proteomic experiment.
