Results of the screening of a library of bioactive compounds (~2000) using three probes: HPr+ in the presence of DNA as a probe for O2Superscript>/Superscript> and CBA or Amplex Red in the presence of HRP as probes for H2O2. (a) Correlation of the results of the three assays for NOX2 activity. (b) Results of screening as a percentage of positive hits in one, two, or all three assays.
