  • Publication number: 20080133143
    Abstract: The present invention generally relates to methods of rapidly and efficiently searching biologically-related data space. More specifically, the invention includes methods of identifying bio-molecules with desired properties, or which are most suitable for acquiring such properties, from complex bio-molecule libraries or sets of such libraries. The invention also provides methods of modeling sequence-activity relationships. As many of the methods are computer-implemented, the invention additionally provides digital systems and software for performing these methods.

  • Publication number: 20080050357
    Abstract: Methods, computer systems, and computer program products for antibody engineering. A variant set for an antibody of interest is constructed by identifying, using a plurality of roles, a plurality of positions in the antibody of interest and, for each respective position in the plurality of positions, substitutions for the respective position. The plurality of positions and the substitutions for each respective position in the plurality of positions collectively define an antibody sequence space. A variant set comprising a plurality of variants of the antibody of interest is selected. A property of all or a portion of the variants in the variant set is measured. A sequence-activity relationship is modeled between (i) one or more substitutions at one or more positions of the antibody of interest represented by the variant set and (ii) the property measured for all or the portion of the variants in the variant set.

  • Publication number: 20070043516
    Abstract: Computer systems, computer program products and methods for designing oligonucleotides are provided. A set of sequence elements is defined. Each sequence element represents an amino acid sequence segment or a nucleic acid sequence segment. The set of sequence elements collectively represent a design nucleic acid sequence. The set of sequence elements are displayed as a plurality icons in a linear or a near linear arrangement such that each respective icon in the plurality of icons uniquely represents a corresponding sequence element in the set of sequence elements. In this representation, neighboring icons in the plurality of icons represent neighboring sequence elements in the set of sequence elements. Each respective icon in the plurality of icons depicts a directional property for the corresponding sequence element in the set of sequence elements. An oligonucleotide selection module is used to identify oligonucleotides in the design nucleic acid sequence.

  • Publication number: 20060136184
    Abstract: Methods, computer systems, and computer program products for biopolymer engineering. A variant set for a biopolymer of interest is constructed by identifying, using a plurality of rules, a plurality of positions in the biopolymer of interest and, for each respective position in the plurality of positions, substitutions for the respective position. The plurality of positions and the substitutions for each respective position in the plurality of positions collectively define a biopolymer sequence space. A variant set comprising a plurality of variants of the biopolymer of interest is selected. A property of all or a position of the variants in the variant set is measured. A sequence-activity relationship is modeled between (i) one or more substitutions at one or more positions of the biopolymer of interest represented by the variant set and (ii) the property measured for all or the portion of the variants in the variant set.
