Figure 1

Microsecond bursts of radicals modify free methionine and BSA in a dose dependent fashion. (A) Left, schematic of sample and instrument. Right, photograph demonstrating treatment in progress. (B) Graph demonstrating µs breakdowns to produce µs bursts of hydroxyl radicals. (C) Production of oxidized methionine with increasing plasma treatment time. For each data point, n = 3 and error bars are ± standard deviation. (D) Modification observed on native (above) and digested (below) BSA with increasing plasma treatment times. Regions shown for comparison have been selected; full data in Fig. S3. For each bar, n = 3 and error bars are ± standard deviation.
