摘要:
The present invention provides a "ASCP-body" that comprises a bottomside epitope binding domain ("BEBD") comprising four Bottomside Binding Regions (BBR1, BBR2, BBR3, and BBR4). This epitope binding domain is in addition to the topside epitope binding domain (TEBD) formed by the three Complementarity Determining Regions (CDR1, CDR2, and CDR3). The invention encompasses mono-specific, bi-specific and multi-specific, and mono-valent, bi-valent and multi-valent ASCP-bodies. The invention also encompasses fusion proteins in which one or more ASCP-bodies with a BEBD is conjugated to one or more ASCP-bodies with a BEBD and, optionally, a TEBD; to one or more ASCP- bodies with a TEBD and, optionally, a BEBD; or to one or more non-ASCP-body entity(ies). The various ASCP-bodies in the bi-specific and multi-specific ASCP-bodies and fusion proteins may all bind to the same epitopes or antigens or may bind to different epitopes or antigens.
摘要(中):
本发明提供了包含四个底部结合区(BBR1,BBR2,BBR3和BBR4)的底部表位结合结构域(“BEBD”)的“ASCP体”。 该表位结合结构域除了由三个互补决定区(CDR1,CDR2和CDR3)形成的顶侧表位结合结构域(TEBD)之外。 本发明包括单特异性,双特异性和多特异性以及一价,一价和多价的ASCP体。 本发明还包括融合蛋白,其中具有BEBD的一个或多个ASCP-体与一种或多种具有BEBD和任选的TEBD的ASCP-体共轭; 具有TEBD和可选的BEBD的一个或多个ASCP体; 或一个或多个非ASCP身体实体。 双特异性和多特异性ASCP体和融合蛋白中的各种ASCP-体都可以结合相同的表位或抗原,或者可以结合不同的表位或抗原。
