This Human Serum Amyloid A Sandwich ELISA Kit from Innovative Research is intended for quantitative detection of human SAA in cell culture supernates, cell lysates, serum and plasma (heparin, EDTA). Strip well format. Reagents for up to 96 tests.
This human SAA Sandwich ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for SAA has been precoated onto 96-well plates. Standards(Expression system for standard: E.coli, Immunogen sequence: S20-Y122) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for SAA is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human SAA amount of sample captured in plate.

Additional Information:
The capture antibody is a monoclonal antibody from mouse, the detection antibody is a biotinylated polyclonal antibody from goat. Expression system for standard: Serum amyloid A protein (SAA), also known as SAA1, is a protein that in humans is encoded by the SAA1 gene. This gene encodes a member of the serum amyloid A family of apolipoproteins. It is mapped to 11p15.1. SAA is a major acute phase protein that is highly expressed in response to inflammation and tissue injury. This protein also plays an important role in HDL metabolism and cholesterol homeostasis. High levels of this protein are associated with chronic inflammatory diseases including atherosclerosis, rheumatoid arthritis, Alzheimer's disease and Crohn's disease. This protein may also be a potential biomarker for certain tumors.; Immunogen sequence: 333
Curious About The Best Way To Thaw Plasma?
- Preheat a water bath to 37 C.
- Place the frozen plasma sample directly in the water bath.
- Gently agitate the plasma sample every 5-10 minutes to insure even thawing.
- The total thawing time will depend on the frozen sample volume. A 10 ml sample might be thawed completely in 5 minutes, but a large sample could take up to 1 hour.
- The thawed sample should be used immediately or stored at 4 C for up to 24 hours. Liquid plasma should never be kept on ice or stored below 0 C as the cold may cause clotting.
- Plasma should be visually inspected for signs of clotting or precipitation before use in experiments. A coagulation test such as aPTT can also be performed to verify the preservation of the hemostasis system.
- Plasma should always be snap-frozen by placing the tube in dry ice for at least 1 hour. Large containers can be covered in dry ice for even freezing.
- Frozen plasma should be stored at –20 C or colder. Lower temperatures will help preserve labile plasma proteins for longer time periods.
This protocol is applicable for plasma containing any anticoagulant of both human and animal origin. While handling serum does not involve the same risk of clotting due to improper handling, we recommend following the above instructions for both plasma and serum for best results
