Background of SP2
Transcription factor Sp2 is a protein that in humans is encoded by the SP2 gene. This gene encodes a member of the Sp subfamily of Sp/XKLF transcription factors. Sp family proteins are sequence-specific DNA-binding proteins characterized by an amino-terminal trans-activation domain and three carboxy-terminal zinc finger motifs. This protein contains the least conserved DNA-binding domain within the Sp subfamily of proteins, and its DNA sequence specificity differs from the other Sp proteins. It localizes primarily within subnuclear foci associated with the nuclear matrix, and can activate or in some cases repress expression from different promoters.
Antibody Validation
Boster validates all antibodies on WB, IHC, ICC, Immunofluorescence, and ELISA with known positive control and negative samples to ensure specificity and high affinity, including thorough antibody incubations.

Western blot analysis of SP2 using anti-SP2 antibody (PB9557).
Electrophoresis was performed on a 5-20% SDS-PAGE gel at 70V (Stacking gel) / 90V (Resolving gel) for 2-3 hours.
Lane 1: Rat Lung Tissue Lysate at 50ug,
Lane 2: A549 Whole Cell Lysate at 40ug,
Lane 3: HELA 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-SP2 antigen affinity purified polyclonal antibody (Catalog # PB9557) 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 SP2 at approximately 72 kDa. The expected band size for SP2 is at 72 kDa.

Question
We are currently using anti-SP2 transcription factor antibody PB9557 for rat tissue, and we are happy with the WB results. The species of reactivity given in the datasheet says human, rat. Is it likely that the antibody can work on canine tissues as well?

Answer
The anti-SP2 transcription factor antibody (PB9557) has not been validated for cross reactivity specifically with canine tissues, though 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 canine you can get your next antibody for free. Please contact me if I can help you with anything.
