An RGD-containing peptide blocks adhesion of A549 cells to LAP and SLC. Adhesion of A549 cells to wells coated with 33 μg/ml LAP (A) or SLC (B) was measured as described in Figure 1. Cells were incubated with the indicated concentrations of an RGD-containing peptide or control (RGE) peptide during the adhesion period. Adhesion is normalized to cells bound to poly-d-lysine in the absence of peptide.
