Serum Amyloid A1 in Human Liver. Serum Amyloid A1 was detected in immersion fixed paraffin-embedded sections of human liver using Mouse Anti-Human Serum Amyloid A1 Monoclonal Antibody (Catalog # MAB30191) at 1 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to hepatocytes.

Background: Serum Amyloid A1
Human serum amyloid A protein-1 (SAA-1) is a multifunctional apolipoprotein produced by hepatocytes in response to proinflammatory cytokines. It is secreted as a 12 kDa, 104 amino acid (aa), nonglycosylated polypeptide that displaces apoA1 in the HDL3 complex (SwissProt #P02735). The SAA-1 gene is one of three SAA genes in human, and it shows multiple alleles that are race dependent. The SAA-1 gene product differs from the SAA-2 gene product by only seven amino acids. Circulating SAA-1 shows multiple proteolytically-generated isoforms, with anywhere from one-to-three amino acids being cleaved from either the N- or C-terminus. Mature human SAA-1 is 72%, 82% and 72% aa identical to mature mouse, rabbit and hamster SAA-1, respectively.
