Comparative evaluation of label-free quantification strategies To compare the performance of widely used or recently developed label-free quantification strategies, we analyzed the data using seven distinct label-free quantification strategies ( Fig. 1 and Supplementary Table S1). MQ-SC and StPeter were based on spectral count, while other strategies were based on ion intensity. Label-free quantification - Wikipedia Label-free quantification is a method in mass spectrometry that aims to determine the relative amount of proteins in two or more biological samples. Unlike other methods for protein quantification, label-free quantification does not use a stable isotope containing compound to chemically bind to and thus label the protein.
