Methods and systems for identifying and/or quantifying polypeptide binding interactions of ligand-binding polypeptides are disclosed. Detailed methods include methods for identifying binding ligands of ligand-binding polypeptides and methods for assessing changes in binding behavior due to alterations of ligand-binding polypeptides. Detailed systems include array-based systems that permit detection of ligand binding interactions at single-analyte resolution.

Described herein is fatty acid-binding protein 3 (FABP3) and/or FABP4 for diagnosing or staging peripheral artery disease (PAD) or for assessing revascularization in PAD afflicted subjects. Also described is FABP3 and/or FABP4 for distinguishing PAD patients from non-PAD patients regardless of the presence PAD symptoms, for distinguishing PAD patients with a non-compressible ABI from non-PAD patients, or for determining prognosis in PAD. Also described herein are various methods and biomarker panels for use in PAD.

A protein scaffold based on a consensus sequence of fibronectin type III (FN3) proteins, such as the tenth FN3 repeat from human fibronectin (human Tenascin), including isolated nucleic acids that encode a protein scaffold, vectors, host cells, and methods of making and using thereof have applications in diagnostic and/or therapeutic compositions, methods and devices. In particular, protein scaffold molecules binding to IgG have been identified as useful for diagnostic and/or therapeutic applications.
