Serum amyloid P component (SAP) is a glycoprotein of interest due to its presence in amyloid plaque formations. As with most glycoproteins, SAP can possibly vary greatly in its isoforms, which can be an important factor towards understanding the role of SAP. Interestingly, previous characterizations suggest varying degrees of microheterogeneity, some of which are in conflict. In this work, we provide new information to clarify SAP’s microheterogeneity profile using capillary isoelectric focusing (cIEF) to carefully analyze pooled samples and by studying individual samples across populations with mass spectrometric immunoassay. With respect to cIEF, a single pI band was observed suggesting that human SAP does not have extensive heterogeneity concluded from gel IEF experiments in the past. Additionally, this is supported by a population study which revealed an overwhelming degree of uniformity. Overall, this work corroborates the idea that SAP is relatively consistent across the population and with respect to microheterogeneity.
