MALDI–TOF-MS analysis of lipid-free apoA-I simultaneously digested by chymase and CPA
Lipid-free apoA-I treated with chymase (grey lines) and chymase/CPA (black lines) for 4 h, as shown in Figure 5, was analysed by MALDI–TOF-MS. The wide-range (from m/z approximately 20000–30000) profile (A) shows two groups of peaks. The small (B) and large (C) rectangles bounded by grey lines indicate areas enlarged in (B) and (C), respectively. Numbers in the Figures indicate m/z.
