Abstract
The present invention relates to immunoglobulins that bind FcγRIIb+ cells and coengage the antigen on the cell's surface and an FcγRIIb on the cell's surface, methods for their generation, and methods for using the immunoglobulins.
Claims
exact text as granted — not AI-modifiedWe claim:
1 . A nucleic acid encoding an Fc variant comprising at least amino acid modifications G236N and S267E as compared to a parent Fc polypeptide, wherein numbering is according to the EU index according to Kabat.
2 . An expression vector comprising the nucleic acid of claim 1 .
3 . A host cell comprising the vector of claim 2 .
4 . A nucleic acid encoding a heavy chain of an antibody, the heavy chain comprising an Fc variant comprising at least amino acid modifications G236N and S267E as compared to a parent Fc polypeptide, wherein numbering is according to the EU index according to Kabat.
5 . An expression vector comprising the nucleic acid of claim 4 .
6 . A host cell comprising the vector of claim 5 .Join the waitlist — get patent alerts
