Galaxy Training: Label-free data analysis using MaxQuant MaxQuant supports different "Quantitation Methods". The three main categories are label-free quantification, label-based quantification and reporter ion MS2 quantification. In this tutorial we have chosen label-free because we did not apply any specific labeling/quantitation strategy to the samples.
