Fig. 2From: Chromatin alterations during the epididymal maturation of mouse sperm refine the paternally inherited epigenomeChanges in select histone posttranslational modifications between mouse caput spermatozoa and cauda sperm. Comparison of select histone posttranslational modifications between immature and mature sperm was conducted using Western blotting. Blots of each histone modification were quantified using ImageJ and normalized to levels of total histone H3. This normalized ratio was compared between caput and cauda sperm. Error bars represent the SEM, n = 3 independent replicates, * p < 0.05, ** p < 0.01Back to article page
