The relationship between the concentration of serum amyloid protein (SAP) isolated from human serum and the parameters of the protein elution during gel-filtration and alos with the efficiency of Ca(2+)-dependent SAP binding with sepharose 4B was studied. The dissociation of the SAP oligomeric form in solution and the interaction of the protein with human serum albumin with fully reduced S--S bridges due to the introduction of the additional hydrophobic surface was shown. Apoprotein E isolated from human plasma very-low-density lipoproteins replaced SAP in the complex with albumin.
