摘要： Methods to screen antibodies against an antigen, categorize them according to the epitope they recognize, and rank them according to their binding affinities, thereby providing a method to rapidly and efficiently identify antibodies having potential usefulness in therapeutic products are described. Also described are methods of evaluating antibodies to determine their potential usefulness in therapeutic products.

摘要： Methods for categorizing antibodies based on their epitope binding characteristics are described. Methods and systems for determining the epitope recognition properties of different antibodies are provided. Also provided are data analysis processes for clustering antibodies on the basis of their epitope recognition properties and for identifying antibodies having distinct epitope binding characteristics.

摘要： Methods are disclosed for determining the relative binding affinities of molecules for their binding partner. One type of molecule is an antibody, which has an antigen binding partner. Antibodies are tested for binding against limited dilutions of antigen. Antibodies that bind to the most dilute antigen concentrations are determined to have a higher relative binding affinity for the antigen than antibodies that only bind to more concentrated antigen preparations.
