Kit Radicaux Libres, A Biological Application for Monitoring Oxidative Stress in Pigs

Figures & data

Figure 1. The overall antiradical capacity (mean±SE) expressed as half haemolysis time (HT₅₀) in whole blood analysed within 3 h (T1), after 24 (T2) and 48 h (T3) of blood collection. A,BMeans within column with different superscript letters differ significantly at P<0.001.

Figure 2. The overall antiradical capacity (mean±SE) expressed as half haemolysis time (HT₅₀) in red blood cell (RBC) analysed within 3 h (T1), after 24 (T2) and 48 h (T3) of blood collection. a,bMeans within column with different superscript letters differ significantly at P<0.05.
