Fig. 3From: Evaluation of sample preparation methods for mass spectrometry-based proteomic analysis of barley leavesQualitative comparison of five different protocols for protein extraction and digestion. Proteins were identified and quantified using label-free proteomics and in at least two out of three replicates. a, distribution of protein sequence coverage; b, percentage of missed cleavages. The protocols are shown in Fig. 1Back to article page
