Whole blood H2S levels in wild type and CSE−/− mice following varying oxygen conditions. Wild type (WT) and CSE−/− mice were either sacrificed under normoxic conditions, or placed in hypoxia (11% O2) for 72 hours prior to sacrifice with twice-daily injections of saline or Na2S. Blood was collected via cardiac puncture at time of sacrifice, and H2S level were measured using a H2S electrode. Values are expressed as mean ± standard deviation. *p<0.05.
