ABSTRACT:
The invention relates to a new method of immunological analysis for serum amyloid A protein (SAA) and serum amyloid P-component (SAP), kits therefor and a method of purification of SAA and SAP. These methods are based on the efficient binding of SAP to a plastic surface and to carriers bearing nitrated phenyl groups in the presence of calcium and related bivalent ions, and of SAA to a plastic surface and to carriers bearing nitrated phenyl groups with or without calcium ions. The method of immunological analysis allows for rapid and reliable screening of serum samples with a high sensitivity. SAA and SAP play a key role in the diagnosis and management of inflammatory diseases.
