Apo-SAA1

Recombinant human Apo-SAA1 is an 11.7 kDa protein containing 105 amino acid residues. Serum amyloid A proteins (SAA) represents a family of apolipoproteins that circulates in association with high-density lipoproteins (HDL) . The level of Apo-SAA usually is 1-5 μg/ml in plasma. It increases 500-1000 fold within 24 hours of an inflammatory stimulus and, under these conditions, is the most abundant HDL Apo-lipoprotein. The human SAA gene codes for a 122 amino acid non-glycosylated polypeptide, which contains an 18 amino acid N-terminal sequence.
