Fig. 3. Discovery proteomics. (A) UpSet plot showing the total number of proteins and sub-units detected per condition, the number of unique proteins and sub-units detected per condition, and intersections of multiple conditions. (B) Dimensions 1 and 2 of Principal Component Analysis (PCA) of various ECM types. Each ECM type had n = 3 replicates (small points) with larger points representing the mean coordinates of the replicates. (C) Heatmap showing the detection or absence of collagens, proteoglycans, and ECM glycoproteins per each ECM type.
