    Abstract: The present invention generally relates to nanolipoprotein particle conjugates comprising at least one polypeptide and nanolipoprotein particle conjugates comprising at least one short peptide between 20-60 amino acids in length. Also provided are related compositions and systems, and methods of preparing and using same. In particular, nanolipoprotein particle (NLP) conjugates with antigen-binding fragments (Fabs) are provided, where the NLP comprises a bilayer of membrane-forming lipids encircled by scaffold proteins, and the Fabs are conjugated to one or both bilayer surfaces. In some embodiments, the (NLP) conjugates further comprise a short peptide 20-60 amino acids in length. The conjugates, and related compositions and systems, generally show good stability and manufacturability, retain antigen-binding activity, and can enhance antigen-binding potency, providing versatile platforms for delivery of Fab and Fab-based therapeutics and diagnostics, as well as providing stable platforms for delivering other therapeutic and/or diagnostic agents.
