    • Trt-S-ON (typically 7 μL of a 0.1 OD per μL, 0.7 OD; 4.16 nmol) was dried in a SpeedVac unit and resuspended in 10 μL of glacial acetic acid. 8.3 μL of a 10 mM solution of 3-nitro-2-pyridinesulfenyl chloride (Cl-NPyS) (8.3 nmol, 20 molar excess) was then added and the reaction was allowed for 1 h. The reaction was monitored by HPLC with a 20 min linear gradient of 12-20% acetonitrile in 50 mM TEAAc, pH 7.2. Prior to HPLC purification, the crude reaction media were resuspended in 500 μL of 50 mM TEAAc and loaded with a manual injector equipped with a 1 mL loop. Analytical HPLC characterization of the activated-ON was performed in the same eluting conditions.

The resulting mixture (1 μL) was spotted on the stainless steel probe tip and left to dry in air. The samples were then subjected to MALDI-TOF analysis.
