Cell surface profiling with peptide libraries yields ligand arrays that classify breast tumor subtypes

Abstract excerpt

Cancer heterogeneity renders risk stratification and therapy decisions challenging. Thus, genomic and proteomic methodologies have been used in an effort to identify biomarkers that can differentiate tumor subtypes to improve therapeutic outcome. Here, we report a generally applicable strategy to generate tumor type-specific peptide ligand arrays. Peptides that specifically recognize breast tumor-derived cell...
