在knob-into-hole技术的基础上,单特异性抗体分子上加了Fc-dummy chains,避免半抗体样分子(half-antibody like molecules)聚集,形成二聚体。在input A和Input B加入的两个半抗体样分子相遇,则发生Format Chain交换,两个Fc-dummy chains带有不同电荷,及Konb和hole,自组装成二聚体(Dummy dimmer)在纯化时,可以被去掉。

However, the bsAb byproducts and impurities, including mispaired homodimers, half-antibodies, light chain mispairings, antibody fragments and high levels of high molecular weight (HMW) species, all pose unique challenges to their downstream processing. Here, using two knob-into-hole (KiH) ...
Structural and Functional Characterization of a Hole-Hole Homodimer Variant in a "Knob-Into-Hole" Bispecific Antibody Compared with the hole–hole homodimer under different storage conditions, the bispecific heterodimer, guided by the knob-into-hole assembly, proved to be a stable conformation with ...
Non-affinity platform for processing knob-into-hole bispecific antibody Bispecific antibodies hold significant potential as next-generation biotherapeutics owing to their ability to simultaneously bind to two targets. However, ... Xiaoyang Wang,Min Li,Mengting Li,... - Bioresources and Bioprocessing 被...
To inhibit B:b interactions of desB-fibrin with fragment D, B-knob was blocked with 100 μg/mL mAb T2G1,48,49 an antibody against the β15-21 portion of fibrin comprising the B-knob (Figure 4D), and b-hole was blocked with either 10 mM GHRPam (Figure 4E) or 37 μM (400 μ...
