Interferon Alpha Active Protein | IFNa active protein
Active Interferon Alpha (IFNa)
20mM Tris, 150mM NaCl, pH8.0, containing 1mM EDTA, 1mM DTT, 0.01% SKL, 5% Trehalose and Proclin300.
Stability: The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37 degree C for 48h, and no obvious degradation and precipitation were observed. The loss rate is less than 5% within the expiration date under appropriate storage condition.

Application Data
(Interferon-alpha (IFN-), also known as leukocyte interferon, represents a group of related but distinct proteins that share over 95% amino acid sequence homology. They are members of the type I interferon family which share a common cell surface receptor composed of two subunits. IFN- has both anti-viral and immunomodulatory activities on target cells. To test the effect of IFN- on cell apoptosis, A549 cells were seeded into 96-well plates at a density of 3,000 cells/well with 1% serum standard DMEM including various concentrations of recombinant human IFN-. After incubated for 48h, cells were observed by inverted microscope and cell proliferation was measured by Cell Counting Kit-8 (CCK-8). Briefly, 10 uL of CCK-8 solution was added to each well of the plate, then the absorbance at 450 nm was measured using a microplate reader after incubating the plate for 2 hours at 37. Proliferation of A549 cells after incubation with IFN- for 48h observed by inverted microscope was shown in Figure 1. Cell viability was assessed by CCK-8 (Cell Counting Kit-8) assay after incubation with recombinant human IFN- for 48h. The result was shown in Figure 2. It was obvious that IFN- significantly inhibit cell viability of A549 cells. The ED50 is 3.4 ug/mL.(A) A549 cells cultured in DMEM, stimulated with 10ug/mL IFN- for 48h;(B) Unstimulated A549 cells cultured in DMEM for 48h.Figure 1.

Product Notes
The IFNa ifna1 (Catalog #AAA150049) is an Active Protein and is intended for research purposes only. The product is available for immediate purchase. The immunogen sequence is Cys24~Leu181. AAA Biotech's Interferon Alpha 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 IFNa ifna1 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. It is sometimes possible for the material contained within the vial of "Interferon Alpha, 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
