Distinguishing of tumor cell-targeting peptide ligands through a color-encoding microarray†
Abstract
A silicon-based microarray system was constructed to discover the affinity peptides and to distinguish the specific peptides from a high throughput library. Using a color-encoding strategy, in situ peptide distinguishing between HER1 ligands and HER2 ligands was achieved. Novel affinity peptide sequences H1P (HER1 ligand) and H2P (HER2 ligand) were determined with nmol affinity.
