    • The present invention is directed to the preparation and use of a collection of antibody heavy chain complementarity determining region 3 (HCDR3) members, where diversity of the collection is a function of the length of the HCDR3 members. The diversity of the collection of HCDR3 regions substantially represents the natural amino acid distribution of HCDR3 in the human repertoire. This natural amino acid distribution can be represented by biasing the complete random distribution of amino acids, accordingly, in the HCDR3 encoding DNA sequence by using trinucleotide mutagenesis (TRIM) technology. A collection of HCDR3 members of the invention each can be comprised within a variable region of an antibody (or fragment thereof) to form a library of synthetic antibodies or antibody fragments. Synthetic antibody libraries of the present invention may be designed to include modular features, such as chemically synthesized "master gene" framework regions, which may contain unique restriction sites flanking one or more CDR regions, including an HCDR3 region prepared as described herein. The invention also provides nucleic acid molecules encoding such diverse collection and methods of making and using the same.
    • 本发明涉及抗体重链互补决定区3(HCDR3)成员集合的制备和应用,其中集合的多样性是HCDR3成员长度的函数。 HCDR3区域集合的多样性基本上代表了HCDR3在人类库中的天然氨基酸分布。 这种天然氨基酸分布可以通过使用三核苷酸诱变(TRIM)技术偏置氨基酸的完全随机分布来表示,因此在HCDR3编码DNA序列中。 本发明的HCDR3成员的集合可以各自包含在抗体(或其片段)的可变区内以形成合成抗体或抗体片段的文库。 本发明的合成抗体文库可以被设计为包括模块化特征,例如化学合成的“主基因” 框架区,其可以包含侧接一个或多个CDR区的独特限制性位点,包括如本文所述制备的HCDR3区。 本发明还提供了编码这些不同收集物的核酸分子以及制备和使用它们的方法。

    • A target internalized within a cell (and a binding member that specifically binds thereto) can be identified in an efficient manner by segregating (or substantially segregating) genetic material encoding the binding member from genetic material encoding a binding member that binds to a target that is not internalized. This can be achieved by employing a display library of binding members having a genotype/phenotype linkage via a non-fusion protein format, whereby genetic material encoding non-internalized targets can be segregated (or substantially segregated) without lysing the cells. Internalized genetic material subsequently can be isolated and amplified.
    • 通过将编码结合成员的遗传物质与编码结合成分的结合成员的遗传物质分离(或基本上分离),可以以有效的方式鉴定内细胞内(特异性结合于其的结合成员)的靶标 没有内化。 这可以通过使用具有通过非融合蛋白质形式具有基因型/表型连接的结合成员的显示文库来实现,由此编码非内化靶的遗传物质可以在不裂解细胞的情况下被分离(或基本上分离)。 随后可以分离和扩增内源遗传物质。
