Fig. 1From: Differential proteomic analysis demonstrates follicle fluid participate immune reaction and protein translation in yakHeatmap, correlation analysis, and principal component analysis (PCA) for the follicle fluid (FF) samples based on quantification of the all identified proteins in yak. a Heatmap shows the global expression difference of the FF samples based on the total identified proteins. b Correlation matrix illustrates correlations among the yak FF samples of the mature and immature FF. c Scree plot exhibits the first six principal component of the PCA for the FF samples. d PCA biplot shows the first two principal components (Dim1 and Dim2). The correlation of each variable with each axis is indicated by the length and angle of lime segments. e Correlation matrix illustrates correlations between each yak FF sample and each principal component of the first five principal components.Back to article page
