Recombinant Human Interferon Regulatory Factor-3 is supplied as a recombinant protein for in vitro research use.

Background

Members of the IFN regulatory factor (IRF) family regulate gene expression critical to immune response, hemopoiesis, and proliferation. IRF-3 is a member of the IRF family, and is distinct from other family members. Its transcriptional activity is regulated solely by posttranslational modifications. It plays a crucial role in activation of innate immunity and inflammation in response to viral infection. IRF-3 mediates IFN-stimulated response element (isre) promoter activation. Functions as a molecular switch for antiviral activity. Dsrna generated during the course of an viral infection leads to IRF3 phosphorylation on the c-terminal serine/threonine cluster. This induces a conformational change, leading to its dimerization, nuclear localization and association with creb binding protein (crebbp) to form dsrna-activated factor 1 (draf1), a complex which activates the transcription of genes under the control of isre. The complex binds to the ie and prdiii regions on the ifn-alpha and ifn-beta promoters respectively. IRF-3 does not have any transcription activation domains.

Product format

Provided as a recombinant protein suitable for in vitro workflows such as binding studies, screening, and assay development. Refer to the specifications table for expression format and molecular properties.

What is the purity of Recombinant Human Interferon Regulatory Factor-3 (Human)?
Greater than 95.0% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE. BioHippo includes a Certificate of Analysis (CoA) confirming purity per lot with every order.
What buffer / formulation is this protein supplied in?
Supplied as: 1mg/ml in phosphate-buffered saline (PBS), pH 7.4. Reconstitute lyophilized material in sterile ultrapure water or the recommended buffer per the datasheet prior to use.
How should Recombinant Human Interferon Regulatory Factor-3 (Human) be stored?
Liquid IRF3 although stable at 10°C for 1 week, should be stored below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles. Prepare single-use aliquots after reconstitution to avoid repeated freeze–thaw cycles.
What expression system was used to produce this protein?
This recombinant protein was expressed in E. coli. The system was selected to achieve high yield, correct folding, and appropriate post-translational modifications.
Is this protein approved for clinical or in vitro diagnostic use?
No. Supplied for Research Use Only (RUO) — not intended for therapeutic applications or in vitro diagnostic procedures.
Can I request a custom size, tag variant, or formulation?
Yes. BioHippo can accommodate custom requests including alternative sizes, His/GST/Fc tag variants, bulk quantities, and custom formulations. See the Customization & Add-ons tab or email support@biohippo.com.
