Amyloid P component, serum (SAP) is the identical serum form of amyloid P component (AP), a 25kDa pentameric protein (1). Serum amyloid P component is a normal plasma protein and a universal non-fibrillar constituent of amyloid deposits. Serum amyloid P (SAP) is a pentraxin similar to C-reactive protein. SAP and CRP are suggested to associate with cardiovascular disease (2, 3). SAP is also suggested to link with Alzheimer's disease (4) and liver disease (5).
