Tetravalent Fabs-In-Tandem immunoglobulins (FIT-Ig™) technology combines Fab fragments of any 2 parental mAbs create a tetravalent, dual-targeting single molecular entity, where the FabA is structurally fused to FabB in tandem at its N-terminus (Fig. 1a). A unique crisscross orientation of 2 sets of VH-CH1 and VL-CL evades any mispairing problem between two short chains and long chain. FIT-Ig have […]

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 […]
