产品描述 概述Serum amyloid A proteins (SAA) represents a family of apolipoproteins that circulates in association with high-density lipoproteins (HDL). The level of apo-SAA, normally 1-5 μg/ml in plasma, 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. Recombinant human apo-SAA1 is an 11.7 kDa protein containing 104 amino acid residues. 使用说明This material is offered by Novin Biotech for research, laboratory or further evaluation purposes.
