LC-MS SIM chromatograms of tryptic in-gel digested SEB peptide ions containing fragments F¹⁷TGLM²¹ENM²⁴K²⁵, Y²¹³LM²¹⁵M²¹⁶YNDNK²²¹, and T¹¹²C¹¹³M¹¹⁴YGGVTEHNGNQLDK¹²⁸. Untreated SEB is shown in red, and 5 μM SEB incubated in 0.1% (4 mM) NVC-422 in 20 mM PBS (pH 7) buffer at 37°C for 15 min is shown in black.
