Background of SF2
SF2, also known as Serine/arginine-rich splicing factor 1 (SRSF1), is a protein that in humans is encoded by the SFRS1 gene. This gene encodes a member of the arginine/serine-rich splicing factor protein family. There is a pseudogene of this gene on chromosome 13. The encoded protein can either activate or repress splicing, depending on its phosphorylation state and its interaction partners. Multiple transcript variants have been found for this gene. ASF/SF2 is necessary for all splicing reactions to occur, and influences splice site selection in a concentration-dependent manner, resulting in alternative splicing.
Antibody Validation

Figure 1. Western blot analysis of SF2/SRSF1 using anti-SF2/SRSF1 antibody (PB9404).
Electrophoresis was performed on a 5-20% SDS-PAGE gel at 70V (Stacking gel) / 90V (Resolving gel) for 2-3 hours. The sample well of each lane was loaded with 30 ug of sample under reducing conditions.
Lane 1: human Hela whole cell lysates,
Lane 2: human SW620 whole cell lysates,
Lane 3: human MCF-7 whole cell lysates,
Lane 4: human 293T whole cell lysates,
Lane 5: rat brain tissue lysates,
Lane 6: rat liver tissue lysates,
Lane 7: mouse brain tissue lysates,
Lane 8: mouse liver tissue lysates.
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-SF2/SRSF1 antigen affinity purified polyclonal antibody (Catalog # PB9404) 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 SF2/SRSF1 at approximately 28 kDa. The expected band size for SF2/SRSF1 is at 28 kDa.

Figure 2. IHC analysis of SF2/SRSF1 using anti-SF2/SRSF1 antibody (PB9404).
SF2/SRSF1 was detected in a paraffin-embedded section of human placenta 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 2 μg/ml rabbit anti-SF2/SRSF1 Antibody (PB9404) overnight at 4°C. Peroxidase Conjugated Goat Anti-rabbit IgG was used as secondary antibody and incubated for 30 minutes at 37°C. The tissue section was developed using HRP Conjugated Rabbit IgG Super Vision Assay Kit (Catalog # SV0002) with DAB as the chromogen.

Question
We are currently using anti-SF2/SRSF1 antibody PB9404 for rat tissue, and we are satisfied with the IHC results. The species of reactivity given in the datasheet says human, mouse, rat. Is it possible that the antibody can work on primate tissues as well?

Answer
The anti-SF2/SRSF1 antibody (PB9404) has not been tested for cross reactivity specifically with primate 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 primate you can get your next antibody for free. Please contact me if I can help you with anything.
