Diabody antibody

WebAbstract. Diabodies are small dimeric bivalent or bispecific antibody fragments formed by cross-over pairing of two single-chain VH-VL fragments (Holliger et al., 1993, Whitlow et al., 1994). Dimer formation is favoured by reducing the linker length between the VH-VL domains from 15–20 amino acids, normally used to generate scFv fragments, to ... WebThe first crystal structure of a diabody, a bivalent antibody fragment, confirms previous predicted structures and techniques for generating bispecific bivalent antibody fragments of considerable therapeutic potential.

WebJan 1, 2024 · The diabody structure is used to form bispecific antibodies by linking different V H and V L domains of two antibodies (e.g., V H A–V L B and V H B–V L A). However, when two different polypeptides are produced within a single cell, purification steps are necessary to obtain the active heterodimeric antibody among the inactive homodimers. WebOne approach to creating more beneficial therapeutic antibodies is to develop bispecific antibodies (bsAbs), particularly IgG-like formats with tetravalency, which may provide several advantages such as multivalent binding to each target antigen.
