Blood group antigen fusion polypeptides and methods of use thereof
The present invention provides compositions and methods for treating or preventing antibody mediated graft rejection.
1 . An absorber comprising a fusion polypeptide, wherein the fusion polypeptide comprises a first polypeptide operably linked to a second polypeptide, wherein the first polypeptide:
(a) is a mucin polypeptide and
(b) is glycosylated by an α1,2 fucosyltransferase and
the second polypeptide comprises at least a region of an immunoglobulin polypeptide.
2 . A method removing an antibody from a biological sample, the method comprising
(a) contacting a biological sample with the absorber of claim 1 to form an absorber-antibody complex; and
(b) removing the complex from the biological sample thereby removing the antibody from the biological sample.
