  • Publication number: 20120129731
    Abstract: The present invention concerns the design and construction of diverse peptide and polypeptide libraries. In particular, the invention concerns methods of analytical database design for creating datasets using multiple relevant parameters as filters, and methods for generating sequence diversity by directed multisyntheses oligonucleotide synthesis. The present methods enable the reduction of large complex annotated databases to simpler datasets of related sequences, based upon relevant single or multiple key parameters that can be individually directly defined. The methods further enable the creation of diverse libraries based on this approach, using multisynthetic collections of discrete and degenerate oligonucleotides to capture the diverse collection of sequences, or portions thereof.

  • Publication number: 20120107871
    Abstract: A method for generating human IgG1 antibodies with enhanced Fc effector function is disclosed. In practicing the method, an IgG1 Fc look-through mutagenesis (LTM) coding library directed at four receptor-contact regions of the Fc CH2 portion in human IgG1. Fc is expressed in a system in which the mutated Fc fragments are displayed on the surfaces of the expression cells. The fragments are then screened for altered binding affinity to a selected Fc receptor or other Fc-binding protein. The selected mutations may be used, in turn, to guide the selection of multiple substitutions in the construction of a walk-through mutation (WTM) library, for generating additional Fc fragment mutations with desired binding properties. The antibodies so produced have a variety of therapeutic and diagnostic applications.
