Publication number: 20180244765Abstract: The present invention relates to the manufacture of a diverse repertoire of functional heavy chain-only antibodies that undergo affinity maturation, and uses thereof. The invention also relates to the manufacture and use of a diverse repertoire of class-specific heavy chain-only antibodies and to the manufacture and use of multivalent polypeptide complexes with antibody heavy chain functionality, preferably antibody heavy chain binding functionality, constant region effector activity and, optionally, additional effector functions. The present invention also relates to a method of generation of fully functional heavy chain-only antibodies in transgenic mice in response to antigen challenge. In particular, the present invention relates to a method for the generation of human antigen-specific, high affinity, heavy chain-only antibodies of any class, or mixture of classes and the isolation and expression of fully functional VH antigen-binding domains.Type: ApplicationFiled: April 16, 2018Publication date: August 30, 2018Applicant: ERASMUS UNIVERSITY MEDICAL CENTRE ROTTERDAMInventors: Franklin Gerardus Grosveld, Richard Willhelm Janssens, Dubravka Drabek, Roger Kingdon Craig

Publication number: 20120151610Abstract: The present invention provides a high affinity, antigen-specific, soluble heavy chain-only antibody which: lacks hallmark camelid-related amino acid substitutions and has FR2 substitutions which are not found in antibodies which comprise heavy and light chain; shows increased net hydrophobicity within CDR1 and an increased number of charged amino acids present in CDR3; and comprises one or more amino acid substitutions within the framework ?-pleated sheet leading to increased net hydrophobicity within FR1 and an increased number of charged amino acids present in FR3. Also provided are VII domains having the same properties, gene segments for their production, methods for their production, transgenic animals and uses of the antibody of the VH domains in therapy.Type: ApplicationFiled: March 19, 2010Publication date: June 14, 2012Applicant: ERASMUS UNIVERSITY MEDICAL CENTERInventors: Roger Kingdon Craig, Franklin Gerardus Grosveld, Richard Willhelm Janssens, Dubravka Drabek, Tao Chen, Ernie De Boer
