Background of IRF5
Interferon regulatory factor 5, also called IRF5 or SLEB10, is a protein that in humans is encoded by the IRF5 gene. IRF5 gene is mapped to 7q32.1. This gene encodes a member of the interferon regulatory factor (IRF) family, a group of transcription factors with diverse roles, including virus-mediated activation of interferon, and modulation of cell growth, differentiation, apoptosis, and immune system activity. Members of the IRF family are characterized by a conserved N-terminal DNA-binding domain containing tryptophan (W) repeats. Multiple transcript variants encoding different isoforms have been found for this gene, and a 30-nt indel polymorphism (SNP rs60344245) can result in loss of a 10-aa segment. This gene is a transcription factor involved in the induction of interferons IFNA and INFB and inflammatory cytokines upon virus infection.
Antibody Validation

Western blot analysis of IRF5 using anti-IRF5 antibody (PB9646).
Electrophoresis was performed on a 5-20% SDS-PAGE gel at 70V (Stacking gel) / 90V (Resolving gel) for 2-3 hours.
Lane 1: Rat Intestine Tissue Lysate at 50ug,
Lane 2: HELA Whole Cell Lysate at 40ug,
Lane 3: COLO320 Whole Cell Lysate at 40ug,
Lane 4: NIH3T3 Whole Cell Lysate at 40ug,
Lane 5: HEPA Whole Cell Lysate at 40ug.
After electrophoresis, proteins were transferred to a nitrocellulose membrane at 150 mA for 50-90 minutes. Blocked the membrane with 5% non-fat milk/TBS for 1.5 hour at RT. The membrane was incubated with rabbit anti-IRF5 antigen affinity purified polyclonal antibody (Catalog # PB9646) at 0.5 μg/mL overnight at 4°C, then washed with TBS-0.1%Tween 3 times with 5 minutes each and probed with a goat anti-rabbit IgG-HRP secondary antibody at a dilution of 1:5000 for 1.5 hour at RT. The signal is developed using an Enhanced Chemiluminescent detection (ECL) kit (Catalog # EK1002) with Tanon 5200 system. A specific band was detected for IRF5 at approximately 56 kDa. The expected band size for IRF5 is at 56 kDa.

IHC analysis of IRF5 using anti-IRF5 antibody (PB9646).
IRF5 was detected in a paraffin-embedded section of mouse spleen tissue. Heat mediated antigen retrieval was performed in EDTA buffer (pH 8.0, epitope retrieval solution). The tissue section was blocked with 10% goat serum. The tissue section was then incubated with 1 μg/ml rabbit anti-IRF5 Antibody (PB9646) overnight at 4°C. Biotinylated goat anti-rabbit IgG was used as secondary antibody and incubated for 30 minutes at 37°C. The tissue section was developed using Strepavidin-Biotin-Complex (SABC) (Catalog # SA1022) with DAB as the chromogen.

Question
We are currently using anti-IRF5 antibody PB9646 for rat tissue, and we are content with the WB results. The species of reactivity given in the datasheet says human, mouse, rat. Is it true that the antibody can work on monkey tissues as well?

Answer
The anti-IRF5 antibody (PB9646) has not been tested for cross reactivity specifically with monkey tissues, but there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in monkey you can get your next antibody for free. Please contact me if I can help you with anything.
