    • 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. The variant set is redefined to comprise variants that include substitutions in the plurality of positions that are selected based on a function of the sequence-activity relationship.

    • A method of designing a polynucleotide sequence encoding a polypeptide sequence of a predetermined polypeptide is provided. A frequency lookup table corresponding to an expression system is obtained. The table comprises a plurality of sequence elements and a plurality of frequency ranges, each frequency range for a corresponding sequence element. Each frequency range is a range of frequencies with which a corresponding sequence element can occur in a polynucleotide. The polynucleotide sequence is defined using the frequency lookup table by determining, for each respective sequence element in the frequency lookup table, whether the respective sequence element encodes a portion of the polypeptide sequence. When the respective sequence element encodes a portion of the polypeptide sequence, the sequence element is incorporated into the polynucleotide at a frequency of occurrence that is within the frequency range specified for the respective sequence element in the lookup table.
    • 提供了设计编码预定多肽的多肽序列的多核苷酸序列的方法。 获得与表达式系统对应的频率查找表。 该表包括多个序列元素和多个频率范围,每个频率范围用于相应的序列元素。 每个频率范围是在多核苷酸中可以发生相应序列元件的频率范围。 使用频率查找表来定义多核苷酸序列,对于频率查找表中的每个相应序列元件,确定各个序列元件是否编码多肽序列的一部分。 当各个序列元件编码多肽序列的一部分时,序列元件以在查找表中对于相应序列元件指定的频率范围内的发生频率被并入多核苷酸。
