Abstract
A method of preparing anti-b amyloid immunoglobulin involves treating human plasma anti-b amyloid immunoglobulin under alkaline conditions, such as at pH 10.25 to 11.75 using diethylamine HCl, to dissociate b amyloid protein therefrom. Typically, the anti-b amyloid immunoglobulin is present in human immunoglobulin preparations obtained from plasma or serum. Anti-b amyloid immunoglobulin prepared by the method is substantially free of b amyloid protein and has therapeutic activity in compositions and/or methods for treating a disease or condition associated with b amyloid plaques, such as Alzheimer's disease.
