METHODS OF POLYPEPTIDE IDENTIFICATION, AND COMPOSITIONS THEREFOR

摘要

Methods are disclosed for identifying one or more proteins or polypeptides comprised by a sample. The methods comprise determining binding of each polypeptide with respect to each binding pool of a plurality of binding pools, wherein each binding pool comprises one or more probes which bind a structure comprised by a protein or polypeptide. In some aspects, polypeptides can be denatured and separated into individual polypeptide strands and immobilized on a solid support prior to determining binding of the binding pools. A protein, polypeptide or polypeptide strand can be identified by searching, in at least one database, for a protein or polypeptide sequence comprising binding pool targets either identical to or most similar to the binding pool targets comprised by the protein, polypeptide or polypeptide strand to be identified. Kits for identifying proteins, polypeptides and polypeptide strands are also disclosed.

1. A method of identifying a protein or polypeptide, the method comprising:
determining presence or absence, in a protein or polypeptide to be identified, of each binding pool target of a plurality of binding pool targets, wherein each binding pool target comprises one or more binding targets for one or more probes comprised by a binding pool wherein each binding pool comprises a plurality of probes, and binds a binding pool target comprised by a population of proteins or polypeptides described in a database; and identifying, in at least one database, a protein or polypeptide comprising binding pool targets most similar to the binding pool targets comprised by the protein or polypeptide to be identified.
