Fig. 8From: An intracellular, non-oxidative factor activates in vitro chromatin fragmentation in pig spermTotal ROS and superoxide levels after incubation of sperm with Mg2+/Ca2+ (A.1 and A.2) or Mn2+/Ca2+ (B.1 and B.2) at different concentrations (0 mM, 0.1 mM, 1 mM, 5 mM, 10 mM and 50 mM) and for different incubation times (0 min, 2 min, 10 min, 30 min, 60 min). Differences between time points within a given concentration are not shownBack to article page
