New York, USA, July 22 2019  Over the past decades, Creative Biolabs has kept collecting hot therapeutic targets and providing a variety of customized bispecific antibody (BsAb)<\/a> products. To help clients obtain the desired the target-product profile, Creative Biolabs now develops different formats of BsAbs with adapted valency, structure, half-life and biodistribution, etc<\/em>.<\/p>\n

Tandem scFvs<\/strong><\/a>: Two or more moieties of scFv string together to form tandem scFv with 1+1 (+1…) antigen-binding, fused by a helical linker or a flexible linker. They are extensively used in cancer immunotherapy. BiTEs (bispecific T-cell engagers) are the most famous tandem scFv that comprises an anti-CD3 scFv and an anti-TAA (tumor-associated antigen) scFv to retarget T cells to tumor-associated cells.<\/p>\n

Diabody<\/strong>: A dimer of scFv consists of VH and VL domains connected by a short peptide linker. Diabody has monovalent specificity for each antigen (1+1 antigen-binding valency).<\/p>\n

Triple Body<\/strong>: It utilizes Fab fragment as scaffold and can lead to 3×1 (trispecific, trivalent), 2+1 (bispecific, bivalent+monovalent), trivalent or 1+1 (bispecific, bivalent) molecule, as well as immunocytokines, immunotoxins, enzyme fusions, etc.<\/p>\n

Fab-IgG<\/strong>: Fab-IgG is a format of appended IgGs, the IgG scaffold with Fab fragment in the N terminus and is easy to express owing to less artificial construct and sequence design, which are symmetric bispecific and tetravalent molecules, 2+2 antigen-binding valency.<\/p>\n

IgG-scFv<\/strong><\/a>: Two scFvs from the same parental antibody are linked to the C terminus of IgG HC. It is bispecifc and tetravalent, 2+2 antigen-binding valency and can be custom-tailored to meet customers’ specific requirements.<\/p>\n

TandAb<\/strong>: TandAb is expressed as a monomeric subunit (single chain Diabody, scDb) with four variable domains from two parental antibodies.<\/p>\n

Single-chain Diabody (scDb)<\/strong>: It is a derivative of Diabody that connects the first chain and the second chain of diabodies by a flexible linker, transforming the heterodimeric format of diabody into a single-chain format. scDb can also be fused with Fc or CH3 domain to exert Fc-mediated functions and\/or extend half-life.<\/p>\n

Single-chain triplebody (Sctb):<\/strong> It has three tandem scFv units, bispecific or trispecific, 2+1 or 1+1+1 antigen-binding valency and allows the recruitment of immune cells to eliminate disease cells, such as tumor cells.<\/p>\n

Tandem Fabs<\/strong>: It comprises two Fabs targeting different epitopes and is bispecific and has monovalent for each antigen specificity (1+1 antigen-binding valency).<\/p>\n

CrossMab<\/strong>: It remains the general structure and size of a conventional IgG. In CrossMAb, KIH (knobs-into-holes) technology is used to permit the heavy chain heterodimerize. Usually, the referred CrossMab is a bispecific, bivalent molecule, 1+1 antigen-binding valency.<\/p>\n

With an exclusive bispecific antibody development platform, Creative Biolabs can provide novel and well-behaving bispecific antibodies for diverse therapeutic applications. More information can be reached at https:\/\/www.creative-biolabs.com\/bsab\/<\/a>.<\/p>\n
