WebAug 31, 2024 · The knobs-into-holes strategy was the first solution to the heavy chain pairing problem ( Ridgway et al., 1996; Atwell et al., 1997 ). This approach focused on mutations within the C H 3:C H 3 interface, which promoted cognate heavy chain heterodimerisation. WebEfficient KIH production can be achieved by manipulating the plasmid ratio between knob and hole, and further improved by addition of prefabricated knob or hole. These studies demonstrate the versatility of Xpress CF in KIH production and provide valuable insights into KIH construct design for better assembly and expression titer.
