Serum Amyloid P (SAP) is a non-fibrillar plasma glycoprotein that belongs to the pentraxin family. It is universally found in amyloid deposits and this is probably due to its specific calcium-dependent binding to motifs present on all types of amyloid fibrils. SAP is also found to prevent fibrillar breakdown by enzymes and it is believed that it helps maintains stability of the amyloid deposits (1,2). It has been shown that SAP binds monocytes with high avidity, but does not bind to erythrocytes, NK cells, T lymphocytes or B lymphocytes (3). SAP production can be induced by exposure to IL-1, IL-6 and IFN-beta. The SAP-inducing activity was neutralized by antibodies to each of the recombinant cytokines (4).
