Western blot analysis was performed on whole cell extracts (20 ug lysate) of Jurkat (Lane 1), HT-29 (Lane 2) and Raji (Lane 3). The blots were probed with ABfinity™ Anti-IRF-7 Rabbit Recombinant Monoclonal Antibody (Product# 700229, 0.5-2 ug/ml) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.4 ug/ml, 1:2500 dilution). A 55 kDa band corresponding to IRF-7 was observed across cell lines tested. Known quantity of protein samples were electrophoresed using Novex® NuPAGE® 12 % Bis-Tris gel (Product # NP0342BOX), XCell SureLock™ Electrophoresis System (Product # EI0002) and Novex® Sharp Pre-Stained Protein Standard (Product # LC5800). Resolved proteins were then transferred onto a nitrocellulose membrane with iBlot® 2 Dry Blotting System (Product # IB21001). The membrane was probed with the relevant primary and secondary Antibody following blocking with 5 % skimmed milk. Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).

ABfinity™ recombinant antibodies are rabbit monoclonal antibodies, unmatched for producing superior results. ABfinity™ antibodies are developed by immunizing animals, screening for functionality, cloning the immunogen-specific antibody genes into high-level mammalian expression vectors, produced on a large scale, and purified with Protein A.
ABfinity™ monoclonal antibodies resemble rabbit monoclonals isolated from serum or produced by hybridomas, but demonstrate greater specificity and sensitivity. Because ABfinity™ recombinant antibodies are derived from cloned DNA sequences of the heavy and light antibody chains, they are not susceptible to cell-line drift or lot-to-lot variation, thus allowing for peak specificity and performance.
Intact IgG appears on a non-reducing gel as ~150 kDa band and upon reduction generating a ~25 kDa light chain band and a ~50 kDa heavy chain.
IRF-7 is one of nine members of the Interferon Regulatory Factor. The IRF7 gene is induced by the Interferon-triggered Jak-STAT pathway and includes two Interferon in the promoter region and an IFN-stimulated response element in the first intron. It has been shown that all elements of IFN responses, whether the systemic production of IFN in innate immunity or the local action of IFN from plasmacytoid dendritic cells in adaptive immunity, are under the control of IRF-7. IRF-7 is similar to IRF-3 in their virus-induced phosphorylation, dimerization, and nuclear transport, but differ in the cell types in which they are expressed and expression levels.
