Proteomic profiling and PCA. (a) The distribution of numbers of matched peptides for each protein. (b) Sperm protein groups identified currently compared with the previous studies. (c,d) Bar plots showing the total number of quantified peptides and proteins per group, with dots representing the quantification for each individual sample. (e) Pearson correlation coefficient plot of proteins identified in the two sample groups using T-PER lysis buffer. (f) Comparison of the number of proteins identified by two lysis buffers. (g) Venn diagram showing the number of proteins identified by the two extraction methods. (h) Hhclust analysis summary for the two sample groups.
