摘要

Human C-reactive protein (CRP) is an acute phase protein which increases in concentration in response to inflammation. CRP has been known to bind with phosphorylcholine in a calcium-dependent manner. In this study, CRP is found to bind to affinity chromatography of negatively-charged epsilon-aminocaproic acid-agarose when calcium ions are present, and to the affinity chromatography of positively-charged omega-aminohexyl-agarose if a normal ionic strength of NaCl exists but calcium ion is not present.
