Bioactivity
(IFN-g is a dimerized soluble cytokine that is the only member of the type II class of interferons. The importance of IFNg in the immune system stems in part from its ability to inhibit viral replication directly and most importantly from its immunostimulatory and immunomodulatory effects. Studies show that IFN-gamma can rapidly regulate STAT activation by IL-10 and alters macrophage responses to IL-10. Thus a functional binding ELISA assay was conducted to detect the interaction of recombinant pig IFN-g and recombinant pig IL-10. Briefly, IFN-g was diluted serially in PBS with 0.01% BSA (pH 7.4). Duplicate samples of 100 ul were then transferred to IL-10-coated microtiter wells and incubated for 1h at 37 degree C. Wells were washed with PBST and incubated for 1h with anti-IFN-g pAb, then aspirated and washed 3 times. After incubation with HRP labelled secondary antibody for 1h at 37 degree C, 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 450/630 nm immediately. The binding activity of recombinant pig IFN-g and recombinant pig IL-10 was shown in Figure 1, the EC50 for this effect is 3.1 ug/mL.)

Product Notes
The IFNg ifng (Catalog #AAA161669) 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 Interferon Gamma (IFNg) 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 IFNg ifng 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: Ser21~Lys1 66. It is sometimes possible for the material contained within the vial of "Interferon Gamma (IFNg), 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
