WebJan 20, 2024 · This is usually achieved via fusion with a large Fc domain, which negates the benefits of the antibody fragment’s small size. In this work, we show that modifying antibody fragments with short FcRn-binding peptide domains that mimic native IgG engagement with FcRn enables binding and FcRn-mediated recycling and transmembrane transcytosis in ...

WebThe long circulation persistence of human serum albumin (HSA) is enabled by its domain III (DIII) interaction with the neonatal Fc receptor (FcRn). A protein scaffold based on HSA DIII was designed. To modify the serum half life of the scaffold, residues H535, H510, and H464 were individually mutated to alanine. WebNov 18, 2013 · The extracellular domain of FcRn (FcRn ECD) from different species has been recombinantly expressed in many different organisms. Although both gram negative bacteria [ 16 ] and yeast [ 17 ] have been used, it is more common to utilize cells from higher eukaryotes such as CHO cells [ 18 ], different derivates of 293T cells [ 19 - 21 ] and High …
