(a) Mean TWIMS drift time profiles obtained following LESA of native myoglobin (holo-) protein spots sampled under native conditions for various dwell times and mean TWIMS drift time profiles obtained following direct infusion electrospray of myoglobin (holo-) under native conditions (orange line) for 7+, 8+, and 9+ charge states. (b) Mean TWIMS drift time profiles of native myoglobin (holo-) protein spots sampled under native conditions following different drying times at 40 s dwell time and mean TWIMS drift time profiles obtained following direct infusion electrospray of holo-myoglobin (orange line) for 7+, 8+, and 9+ charge states. (c) Mean TWIMS drift time profiles of native myoglobin (holo-) droplets sampled with “liquid LESA” under native conditions at different dwell times and mean TWIMS drift time profiles obtained following direct infusion electrospray of native myoglobin (holo-) (orange line) for 7+, 8+, and 9+ charge states.) (d) Mean TWIMS drift time profiles of denatured myoglobin (apo-) protein spots sampled under native conditions for various dwell times and mean TWIMS drift time profiles obtained following direct infusion electrospray of myoglobin (apo-) under denaturing conditions (orange line) for 7+, 8+, and 9+ charge states.
