Figure 2.
Comparison of glutathione S-transferase enzymatic activity between mite populations. GST activity was determined by a fluorometric assay measuring the conjugation of monochlorobimane to reduced glutathione. Permethrin resistant mites and human mites both display significantly (***, p < 0.0001) elevated GST activity compared to permethrin naïve mites. Bars represent median +/- SEM, n = 3 (protein extracts from female mites).
