Construction, expression, and activity of a bivalent bispecific single-chain antibody.
This report describes the design, construction, and expression of a bivalent bispecific single-chain antibody (SCA) protein in Escherichia coli. The bispecificity of the bivalent protein was based on two previously constructed monovalent single-chain antibody molecules possessing distinct specificities, SCA 4-4-20 (anti-fluorescein) and SCA 04-01 (anti-single-stranded DNA). A flexible linker, m...
متن کاملConstruction of a Mammalian IRES-based Expression Vector to Amplify a Bispecific Antibody; Blinatumomab
Blinatumomab, the bispecific T cell engager, has been demonstrated as the most successful BsAb to date. Throughout the past decade, vector design has great importance for the expression of monoclonal antibody in Chinese hamster ovary (CHO) cells. It has been indicated that expression plasmids based on the elongation factor-1 alpha (EF-1 alpha) gene and DHFR selection marker can be highly effect...

متن کاملConstruction and expression of D-dimer and GPIIb/IIIa single-chain bispecific antibody
The aim of this study was to construct a plasmid expressing glycoprotein IIb-IIIa (GPIIb/IIIa) and D-dimer single-chain bispecific antibody for the targeted therapy of thrombosis. The phosphorylated gene encoding the anti-GPIIb/IIIa single-chain variable fragment (scFv) and the gene encoding the anti-D-dimer scFv were amplified by PCR and linked in tandem by blunt-end ligation. The recombinant ...
متن کامل"Diabodies": small bivalent and bispecific antibody fragments.
Bivalent and bispecific antibodies and their fragments have immense potential for practical application. Here we describe the design of small antibody fragments with two antigen-binding sites. The fragments comprise a heavy-chain variable domain (VH) connected to a light-chain variable domain (VL) on the same polypeptide chain (VH-VL). By using a linker that is too short to allow pairing betwee...
