Abstract (en)

[origin: WO9925379A1] The invention relates to modified immunoglobulin molecules in which one or more variable region residues that form intrachain disulfide bonds are substituted with amino acid residues that do not contain sulfydryl groups, such that the intrachain disulfide bond does not form. Such immunoglobulin molecules have an enhanced ability to elicit an anti-idiotype response. The invention further provides for the methods of prevention and treatment of cancer and/or infectious diseases using the modified immunoglobulins of the invention.
