Anti-U2AF65/U2AF2 Antibody Picoband®

Western blot analysis of U2AF2 using anti-U2AF2 antibody (A03639-2).
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 50ug of sample under reducing conditions.
Lane 1: human HEK293 whole cell lysates,
Lane 2: human THP-1 whole cell lysates,
Lane 3: human U2OS whole cell lysates,
Lane 4: rat brain tissue lysates,
Lane 5: rat spleen tissue lysates,
Lane 6: mouse brain tissue lysates.
After Electrophoresis, proteins were transferred to a Nitrocellulose membrane at 150mA 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-U2AF2 antigen affinity purified polyclonal antibody (Catalog # A03639-2) 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 U2AF2 at approximately 65KD. The expected band size for U2AF2 is at 65KD.

IHC analysis of U2AF2 using anti-U2AF2 antibody (A03639-2).
U2AF2 was detected in paraffin-embedded section of human mammary cancer tissue. Heat mediated antigen retrieval was performed in EDTA buffer (pH8.0, epitope retrieval solution). The tissue section was blocked with 10% goat serum. The tissue section was then incubated with 1μg/ml rabbit anti-U2AF2 Antibody (A03639-2) 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.

IF analysis of U2AF2 using anti-U2AF2 antibody (A03639-2).
U2AF2 was detected in immunocytochemical section of Hela cells. Enzyme antigen retrieval was performed using IHC enzyme antigen retrieval reagent (AR0022) for 15 mins. The cells were blocked with 10% goat serum. And then incubated with 2μg/mL rabbit anti-U2AF2 Antibody (A03639-2) overnight at 4°C. DyLight®488 Conjugated Goat Anti-Rabbit IgG (BA1127) was used as secondary antibody at 1:100 dilution and incubated for 30 minutes at 37°C. The section was counterstained with DAPI. Visualize using a fluorescence microscope and filter sets appropriate for the label used.

Lane 1: A549 whole cell lysates (30ug),
Lane 2: Rabbit control IgG instead of anti-U2AF2 antibody in A549 whole cell lysate,
Lane 3: anti-U2AF2 antibody (2μg) + A549 whole cell lysate (500μg).
After electrophoresis, proteins were transferred to a membrane. Then the membrane was incubated with rabbit anti-U2AF2 antigen affinity purified polyclonal antibody (A03639-2) at a dilution of 1:50 and probed with a mouse anti-rabbit IgG-HRP secondary antibody (Light Chain). The signal is developed using ECL Plus Western Blotting Substrate (Catalog # AR1197). A specific band was detected for U2AF2 at approximately 65 kDa. The expected band size for U2AF2 is at 53 kDa.
