Methods for H2S measurements

With both the acidic and alkaline single time point assays, it remains unclear if acid labile H2S or desulfuration of proteins [40], respectively, creates artifactual overestimates of free H2S levels, as described earlier. Tissue H2S concentrations determined by thiol derivatization using bromobimane near neutral pH followed by HPLC also indicate
