Human Serum amyloid A (SAA) ELISA Kit

Serum amyloid A protein is a protein encoded by the SAA1 gene.The serum amyloid A (SAA) protein is an acute phase apolipoprotein reactant produced mainly by hepatocytes and under regulation of inflammatory cytokines (summarized by Lundmark et al., 2002) . The SAA cleavage product, designated amyloid protein A (AA), is deposited systemically as amyloid in vital organs including the liver, spleen, and kidneys in patients with chronic inflammatory diseases. There is very limited structural information about SAA because of its inherent poor solubility in the apolipoprotein form. It is intriguing to understand how such a small protein is able to mediate or directly carry out such a wide range of functions related to inflammatory reaction and other hostdefense mechanisms.

Human Serum amyloid A (SAA) ELISA Kit has high sensitivity and excellent specificity for detection of Human SAA2. No significant cross-reactivity or interference between Human SAA2 and analogues was observed.

This Human Serum amyloid A (SAA) ELISA Kit employs a two-site sandwich ELISA to quantitate SAA2 in samples. An antibody specific for SAA2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anySAA2 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for SAA2 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of SAA2 bound in the initial step. The color development is stopped and the intensity of the color is measured.

• Do not mix components from different kit lots or use reagents beyond the kit expiration date.• Allow all reagents to warm to room temperature for at least 30 minutes before opening.• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.• Unused wells must be kept desiccated at 4 °C in the sealed bag provided.• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.• It is recommended that all samples and standards be assayed in duplicate or triplicate.
