Fig 9. Inhibitory effect of PDGFR-alpha-derived peptides.

Fig 9

The luciferase reporter virus TB40-BAC4-IE-Gluc was preincubated with 40mer peptides derived from the extracellular domain of PDGFR-alpha at concentrations from 0.05–50 nmol/ml for 2 h before infection of fibroblasts (HFFs) and endothelial cells (HECs). Untreated virus was used as a control for uninhibited infection. One day postinfection, supernatants were analyzed for luciferase activity indicating the degree of infection. The extent of inhibition was calculated as 1 - (luminescence with peptide / luminescence without peptide) and is given as percentage. Error bars indicate the standard error of the mean (SEM) of four data sets per peptide. The number of the peptide (#1-#17) indicates its position in the protein, starting from the N-terminus. Arrowheads indicate the concentration at which 50% of infection are inhibited.
