37226 and 457.20816, respectively. The SRM method used in the MS/MS confirmation protocol presented high specificity and sensitivity. The selected product ions for dermorphin were 602.2, 202.1 and 574.3 and for dermorphin (1-4) were 207.1, 223.1, and 235.1. Both methods were evaluated for specificity, repeatability, carryover, matrix effects, and recovery. No carryover and matrix effects were detected. The limit of detection for initial testing procedure and the limit of identification for confirmation procedure was 2.5 ng/ml. A
