Figure 1From: Physicochemical and biological characterization of 1E10 Anti-Idiotype vaccineRepresentative MALDI-TOF spectrum of 1E10 ST (upper panel) and 1E10 AF (lower panel). Sequences containing N-terminal pyroglutamic acid and methionine 396 are shown at their corresponding m/z. The 16 Da mass shifts corresponding to methionine oxidation is illustrated. Mass values corresponding to methionine oxidation were not detected in 1E10 LAM.Back to article page
