20120077691 | METHOD OF ANALYZING BINDING INTERACTIONS - The invention is directed to methods for obtaining statistically significant information about how structural elements of proteins, e.g. position and identity of amino acid residues in binding domains, relate to functional properties of interest, such as binding affinity, specificity, and the like. In some embodiments, such information is collected by reacting under binding conditions a focused library of candidate nucleic acid-encoded binding compounds with a ligand, so that complexes form between the ligand and a portion of the candidate binding compounds (“binders”). Samples of binders and non-binders arc then decoded by high throughput nucleic acid sequencing to give statistically significant data about the binding properties of substantially all of the candidate binding compounds, permitting them to be ranked by their respective affinities or dissociation constants. A reference compound, such as a pre-existing antibody, may be included in the reaction to identify candidates with similar or improved binding characteristics that have additional desirable characteristics, such as higher solubility, reduced immunogenicity, higher stability, or the like. | 03-29-2012 |
20120258866 | MULTI-DIMENSIONAL SELECTION OF PROTEIN MUTANTS USING HIGH THROUGHPUT SEQUENCE ANALYSIS - The invention is directed to methods for simultaneously improving a plurality of characteristics of a protein binding compound. In accordance with one aspect of the invention, a focused library of nucleic acid-encoded variants is produced and separately exposed to a plurality of reaction conditions each designed to segregate the library variants according to a different characteristic of interest, such as affinity, stability, cross-reactivity, or the like. In various embodiments, such reactions may be conducted pair-wise to simultaneously obtain improvements in two characteristics or they may be conducted three-at-a-time to simultaneously obtain improvements in three characteristics. In each case, nucleotide sequences encoding library variants segregated into improved subsets are determined, after which sequences occurring in two or more subsets are identified to obtain library variants with two or more improved characteristics. | 10-11-2012 |
20130338017 | METHODS OF SCREENING COMPLEX PROTEIN LIBRARIES TO IDENTIFY ALTERED PROPERTIES - The invention provides methods of making designed and constructed protein (e.g., antibody) libraries and libraries resulting from the same. | 12-19-2013 |
20130338038 | METHOD OF SCREENING COMPLEX PROTEIN LIBRARIES TO IDENTIFY ALTERED PROPERTIES - The invention provides methods of making designed and constructed protein (e.g., antibody) libraries and libraries resulting from the same. | 12-19-2013 |
20140235483 | PARALLEL DETERMINATION OF COMPETITIVE BINDING AND TARGET SPECIFICITY OF A BINDING COMPOUND LIBRARY BY HIGH-THROUGHPUT DNA SEQUENCING - The invention is directed to a method for analyzing the competitive binding and target (or ligand) specificity of large numbers of candidate binding compounds with respect to a predetermined reference compound. That is, the invention provides a method for essentially conducting a massively parallel ELISA on each member of an entire library of candidate binding compounds at the same time. Instead of determining binding characteristics from a series of colorimetric or fluorometric readouts, such characteristics are determined from a series of frequencies of bound and unbound library members which, in turn, are determined by high-throughput sequencing of their encoding nucleic acids. In one aspect, predetermined reference compounds are proteins and candidate binding compounds are members of a mutant library based on or related to, the predetermined reference compound. | 08-21-2014 |
