Figure 3

Cell binding assay patterns. Graph lines to the left show: (■) total binding; cells plus radio-labelled peptide, (○) non-specific binding; cells, radio-labelled peptide and excess unlabelled peptide representing residual radio-labelled peptide bound with added 400x concentration of identical unlabelled peptide, (▲) specific binding = [total binding - non-specific binding]. The upper panel shows a strongly bound peptide (e.g. 37768), the central panel shows a non-specific binding peptide (e.g. 37769) and the lower panel a A549 cell binding peptide having low binding activity (e.g., 37770).
