Mouse SAA ELISA Kit ab157723 is a sandwich ELISA to measure Mouse SAA in serum, plasma with a sensitivity of 10.7 ng/ml.
How the assay works
In this assay the SAA present in samples reacts with the anti-SAA antibodies which have been adsorbed to the surface of polystyrene microtitre wells. After the removal of unbound proteins by washing, anti-SAA antibodies conjugated with horseradish peroxidase (HRP), are added. These enzyme-labeled antibodies form complexes with the previously bound Serum Amyloid A. Following another washing step, the enzyme bound to the immunosorbent is assayed by the addition of a chromogenic substrate, 3,3',5,5'-tetramethylbenzidine (TMB). The quantity of bound enzyme varies directly with the concentration of SAA in the sample tested; thus, the absorbance, at 450 nm, is a measure of the concentration of Serum Amyloid A in the test sample. The quantity of SAA in the test sample can be interpolated from the standard curve constructed from the standards, and corrected for sample dilution.
Assay Specificity
Our ELISA kits are rigorously validated to ensure the highest level of consistency and reproducibility. Please check the protocol booklet for more details

Serum Amyloid A (SAA) is an important acute-phase protein with a mass of approximately 12 kDa. It plays a role in inflammation and is present in the serum. SAA is an apolipoprotein that associates with high-density lipoprotein (HDL) during inflammatory states. The protein is expressed mainly in the liver and circulating SAA levels greatly increase during inflammatory responses marking it as an important marker for inflammation.
Biological function summary
SAA contributes to the body's immune response to injury by recruiting immune cells and facilitating the removal of cholesterol. As part of the acute-phase response SAA integrates into HDL displacing other apolipoproteins and altering HDL's function. Increased SAA levels can also modulate prostaglandin synthesis and secretion influencing the inflammatory response. The exact role of SAA in pathways beyond these functions continues to be a subject of research.
Pathways
SAA influences lipid metabolism and inflammatory pathways. It plays a significant role within the acute-phase response pathway which modulates the immune system's reaction to stress such as infection or injury. Another pathway involves cholesterol metabolism where SAA interacts with apolipoproteins AI and AII altering the composition and function of HDL particles.
High levels of SAA associate with amyloidosis and chronic inflammatory diseases. In amyloidosis misfolded SAA proteins deposit as amyloid fibrils in tissues leading to organ dysfunction. In dogs and other species SAA is used as a biomarker to monitor inflammatory diseases. Its connection with C-reactive protein further emphasizes its role in inflammatory processes. Research continues to explore how modulating SAA levels may impact disease progression and treatment.
