Figure 2. The levels of FGF21 processed products in healthy volunteer donors.

FGF21 from 5 ml of donor samples were enriched using an anti-FGF21 antibody, and analysed using LC-MRM. The percentages of the degraded products in each donor sample were plotted. (A) The N-terminal full-length (FL_N), ΔN2 and ΔN4 forms of FGF21; (B) the C-terminal full-length (FL_C) and ΔC10 forms of FGF21.
