Format of bispecific antibodies (BsAbs)-cH IgG1

cH IgG1 / κλ body involves the formation of in vitro display libraries with common heavy chains against two different antigens. κλ body share the same heavy chain but carry either κ or λ light chains. Three different chains (one heavy and two light) are then co-expressed in a single cell to generate a mixture containing two […]

Format of bispecific antibodies (BsAbs)-Hetero H, forced HL IgG1

Hetero H, forced HL IgG1/ DuetMab replaces the native disulfide bond in the CH1-CL interface with an engineered disulfide bond (fig. 1). This enhances cognate light chain pairing. Three different positions in the CH1-CL interface are possible candidates for favoring the formation of a novel disulfide bond. An amino acid on the HC and one […]

Bispecific antibodies: formats, applications and products

Table of Contents Products Introduction Bispecific antibodies (BsAbs) are antibodies with two binding sites directed at two different antigens or two different epitopes on the same antigen. A bispecific antibody (bsAb) is designed and manufactured—through genetic recombination, chemical conjugation, or quadromas—to contain two target‐binding units in one antibody‐based molecule, whereby each unit independently recognizes its […]
