摘要: The invention provides polypeptides comprising a variant heavy chain variable framework domain (VFR). In some embodiments, the amino acids defining the VFR form a loop of an antigen binding pocket. In an embodiment, the polypeptide is a variable domain of a monobody and has a variant VFR. The polypeptide may optionally comprise one or more complementary determining regions (CDRs) of antibody variable domains. In an embodiment, the polypeptide is a variable domain of a monobody and has a variant VFR and one or more variant CDRs. Libraries of polypeptides that include a plurality of different antibody variable domains generated by creating diversity in a VFR, and optionally, one or more CDRs are provided and may be used as a source for identifying novel antigen binding polypeptides that can be used therapeutically or as reagents. The invention also provides fusion polypeptides, compositions, and methods for generating and using the polypeptides and libraries.

摘要: A combinatorial method that uses statistics and DNA sequence analysis rapidly assesses the functional and structural importance of individual protein side chains to binding interactions. This general method, termed “shotgun scanning”, enables the rapid mapping of functional protein and peptide epitopes and is suitable for high throughput proteomics.

摘要: Described herein are peptides and peptide-antibody fusions that bind to the SARS-CoV-2 S protein and the receptor binding domain (RED), and methods for using the compositions containing these antibodies in the treatment of COVID-19, Specifically, we developed novel CoV-2 S protein binding peptides making use of a naïve phage-displayed 16mer peptide library—wherein the CoV-2 S protein binding peptides bind epitopes in both the RBD and S protein outside of the RBD. In addition, we show that fusion of these peptides to the N-terminus of nAbs improves their apparent affinity, potency and breadth of neutralization, without compromising their developability profile, Thus, these peptides represent a novel class of SARS-CoV-2 S protein binders, which can be formatted in various ways to improve functional properties of nAbs to be used in the treatment of many different diseases.

摘要: The invention provides variant CDRs comprising highly restricted amino acid sequence diversity. These polypeptides provide a flexible and simple source of sequence diversity that can be used as a source for identifying novel antigen binding polypeptides. The invention also provides these polypeptides as fusion polypeptides to heterologous polypeptides such as at least a portion of phage or viral coat proteins, tags and linkers. Libraries comprising a plurality of these polypeptides are also provided. In addition, methods of and compositions for generating and using these polypeptides and libraries are provided.
