Protein Length
Full Length
Tag Info
N-terminal 10xHis-tagged and C-terminal Myc-tagged
Form
Liquid or Lyophilized powder
Note: We will preferentially ship the format that
we have in stock, however, if you have any special requirement for the format, please remark your
requirement when placing the order, we will prepare according to your demand.
Buffer
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the
glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer,
6% Trehalose, pH 8.0.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw
cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature
and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized
form is 12 months at -20°C/-80°C.
Lead Time
3-7 business days
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Description
CUSABIO transfected the expression vector which inserted the recombinant DNA into the yeast, cultured the cells, and then induced the transcription and translation of the cloned vector. The N-terminal 10xHis tag and C-terminal Myc tag sequence was appended to the gene coding for the yeast of the mouse Irf3 protein to form the recombinant DNA. The recombinant mouse Irf3 was expressed as N-terminal 10xHis-tagged and C-terminal Myc-tagged fusion. The purity of the protein is greater than 90% assayed by SDS-PAGE. It has an apparent molecular weight of approximately 50 kDa.
IFN regulatory factor-3 (IRF-3) is a transcription factor that plays a central role in the host IRF-3 regulates genes in the innate immune response. As a key regulator, IRF-3 influence the IFN-α/β gene expression. IRF-3 activation and, as a consequence, IFN-β mRNA induction are inhibited in wild-type (PR8) influenza virus-infected cells but not in cells infected with an isogenic virus lacking the NS1 gene. Studies found that positiveregulationofinterferon regulatory factor 3activation by Herc5 via ISG15 modification. In addition, ubiquitously expressed IRF-3 is directly activated after virus infection and functions as a key activator of the immediate-early alpha/beta interferon (IFN) genes, as well as the RANTES chemokine gene.
