Abstract

Official abstract text for this publication.

The invention provides a polypeptide containing at least one IgG Fc region region, said polypeptide having a higher anti-inflammatory activity and a lower cytotoxic activity as compared to an unpurified antibody and methods of production of such polypeptide.

First claim

Opening claim text (preview).

What is claimed is: 1. A modified IVIG composition prepared from an unmodified IVIG composition, wherein the modified IVIG composition has (i) increased anti-inflammatory activity as compared to the unmodified IVIG composition, and (ii) a higher content of α2,6 linked sialic acid in the N-linked glycans of Fc regions than the unmodified IVIG composition. 2. The modified IVIG composition of claim 1 wherein the modified IVIG composition has a higher a higher content of α2,6 linked N-acetylneuraminic acid in the N-linked glycans of Fc regions than the unmodified IVIG composition. 3. A pharmaceutical composition comprising the modified IVIG composition of claim 1 and a pharmaceutically acceptable carrier. 4. A pharmaceutical composition comprising the modified IVIG composition of claim 2 and a pharmaceutically acceptable carrier.
