Sample qualification. A FPKM box diagram. The abscissa in the figure represents different samples. The ordinate represents the logarithm of the sample expression FPKM. The figure measures the expression level of each sample from the perspective of the overall dispersion of the expression amount. B The Pearson correlation of all samples. C Overview of protein identification. D Principal component analysis (PCA) to evaluate the repeatability of protein quantification
