Bioactivity
(Serum Amyloid A2 (SAA2) is a multifunctional apolipoprotein that belongs to SAA family. SAA2 is produced by hepatocytes in response to pro-inflammatory cytokines and is the most prominent members of the acute phase response (APR) during which their serum levels rise dramatically after trauma, infection and other stimuli. Besides, Apolipoprotein C3 (APOC3) has been identified as an interactor of SAA2, thus a functional binding ELISA assay was conducted to detect the interaction of recombinant human SAA2 and recombinant human APOC3. Briefly, SAA2 were diluted serially in PBS, with 0.01% BSA (pH 7.4). Duplicate samples of 100 ul were then transferred to APOC3-coated microtiter wells and incubated for 2h at 37 degree C. Wells were washed with PBST and incubated for 1h with anti-SAA2 pAb, then aspirated and washed 3 times. After incubation with HRP labelled secondary antibody, wells were aspirated and washed 5 times. With the addition of substrate solution, wells were incubated 15-25 minutes at 37 degree C. Finally, add 50 uL stop solution to the wells and read at 450 nm immediately. The binding activity of recombinant human SAA2 and recombinant human APOC3 was shown in Figure 1, and this effect was in a dose dependent manner.)

Product Notes
The SAA2 saa2 (Catalog #AAA161860) is an Active Protein produced from E Coli and is intended for research purposes only. The product is available for immediate purchase. AAA Biotech's Serum Amyloid A2 (SAA2) can be used in a range of immunoassay formats including, but not limited to, Activity Assay, Cell Culture. Researchers should empirically determine the suitability of the SAA2 saa2 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. The amino acid sequence is listed below: Arg19~Tyr1 22. It is sometimes possible for the material contained within the vial of "Serum Amyloid A2 (SAA2), Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
