    摘要: The present invention provides methods for reducing the amidolytic and anti-complement activity (ACA) content of an immunoglobulin composition through the use of cation exchange chromatography. In a specific embodiment, the invention provides methods for reducing the Factor XI and/or Factor XIa and/or ACA content of an immunoglobulin composition by collecting the leading portion of a cation exchange eluate. The present invention also provides immunoglobulin composition having reduced levels of amidolytic activity, Factor XI, and/or Factor XIa, and/or ACA content.

    摘要: The present invention provides analytical methods for detecting anti-polymer antibody in an individual. The methods involve contacting a sample from the individual with a water soluble polymer-modified carrier and detecting binding of antibody to the water soluble polymer on the water soluble polymer-modified carrier wherein binding is indicative of the presence of antibody to the water polymer-modified polypeptide. Antibody may be detected to water soluble polymers such as polyethylene glycol, polysialic acid, dextran, hydroxyalkyl starch, or hydroxyethyl starch. When antibody to the water soluble polymer polyethylene glycol is to be detected, the carrier is modified with a non-linear polyethylene glycol derivative.
