Since 1975, monoclonal antibodies have been successfully used for the diagnosis and therapeutics. In 1993, heavy-chain-only antibodies which bind to antigens was discovered in camelids. The variable domain of heavy chain antibody (VHH) was called as nanobodies and it was anticipated as the better therapeutic antibodies in future due to its high stability, refoldability, and manipulable characteristics. […]

CODV (cross-over dual variable domains) -Ig, contain four polypeptide chains that form two dual variable domains (four antigen binding sites) with a cross-over orientation (Figure 1), which is attained by inverting the alignment of the cognate domains on one chain. In order to adopt the correct VH/VL pairing, linker combinations were designed and optimized using […]
The XmAb enables alterations with desirable effects to the Fc domain of the antibodies. The modification increases affinity to the neonatal Fc receptor which prevents the antibody from degradation. Hence, this interaction extends the antibody’s halflife of this therapeutic drug. In order to construct the XmAb format an antibody heavy and light chain and a […]
CrossMab technology enforces correct light chain association based on the domain crossover of immunoglobulin domains in the Fab region of the bispecific antibody. CrossMab technology allow the generation of various bispecific antibody formats, including bi- (1+1), tri- (2+1) and tetra-(2+2) valent bispecific antibodies, as well as non-Fc tandem antigen-binding fragment (Fab)-based antibodies. These formats may […]
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 […]
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 […]

The production of bispecific antibodies involves the addition of a second antigen-binding site in the Fab arms. Sometimes, these types of bispecific products have problems such as poor stability, immunogenicity and challenges in the manufacturing process. Hence, Mab2 simply replaces the Fc region of an existing antibody with an Fcab that binds to a second […]
ADAPTIR-FLEX platform technologies can be used to produce monospecific, bispecific, and multispecific immunotherapeutic proteins. These protein candidates bind to one or more targets found on tumor cells, immune cells, or other cells in the body or circulation to either amplify, suppress, or regulate the body’s defense mechanisms to treat cancer and autoimmune diseases. ADAPTIR-FLEX molecules […]
