Figure 4: DNA content expressed as μg/10 mg per wet tissue weight in CorMatrix® SIS-ECM (A), tuna cornea (B) and equine pericardial patch (C). Ten different samples were analyzed for each tissue (open bar) and mean value ± SD is represented by the filled grey bar. For all tissues the differences within the single specimen (samples 1-10) was not resulted statistically significant (p>0.05).
