Fig. 3. Inhibition of response by NaHCO3. (A) Time scans and (B) integrated intensity of the chemiluminescent emission of 20 μM PNCL, 200 μM ONOO– and 0 (blue trace), 1 mM, 2 mM, 3 mM, 4 mM, and 5 mM (red trace) NaHCO3. (C) Time scans and (D) integrated intensity of the chemiluminescent emission of 20 μM PNCL, 200 μM Angeli's salt and 0 (blue trace), 1 mM, 2 mM, 3 mM, 4 mM, and 5 mM (red trace) NaHCO3. All experiments were performed in 20 mM HEPES (pH 7.4), containing <1% DMSO.
