Anti-NP1 and anti-KDR peptide binding. Tumour and endothelial cells were incubated with 5-(6)-carboxyfluorescein-labelled anti-NP1 and anti-KDR peptides on chamber slides for 18 h. Peptide binding to the VEGF receptors, NP-1 and KDR, was examined on 4T1 (A), MDA-MB-231 (B) and HUVEC (C) cells by confocal microscopy (× 400 magnification). Images are representative of a scan zoom of between 1- and –4.2-fold.
