Figure 4.

Relative quantitation of peptides. A – Five peptides containing no Methionines (see Table 3) prior to (open bars) and after the depletion using Met-reactive beads (filled bars). B – Five peptides containing Methionines (see Table 3) prior to (open bars) and after the depletion using Met-reactive beads. No Met-containing peptides were detected in the depleted samples. Bar heights (both panels) represent averaged peak values detected (+/- STDEV, n = 9). Peptides are identified by their Seq IDs below each bar (on both panels).
