Isolation and partial characterization of SAA-an amyloid-related protein from human serum.


A 12,000 dalton serum amyloid A protein (SAA) has been isolated by chromatography on Sephadex in 10% formic acid. It is similar immunologically to the previously characterized 8500 dalton tissue amyloid A (AA) protein. The results of amino acid analyses, peptide maps, and the identity of the first 11 residues of the SAA and AA proteins support the idea that… (More)
