FAP activity in serum correlates with liver disease and FAP levels. (A) Scatter plot showing FAP activity levels determined by using the aP peptide (x axis) and FAP protein levels determined by ELISA in serum samples (y axis) from healthy individuals (N = 16, black circles) or individuals previously diagnosed with liver cirrhosis (N = 17, red circles). R2 value is indicated in the graph. (B and C) The same data as (A), with FRET and ELISA data presented separately, including mean ± SEM. P values indicated were calculated by student t-test.
