Western blot analysis of DBF4 using anti-DBF4 antibody (orb654419). 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 HepG2 whole cell lysates, Lane 2: human SH-SY5Y whole cell lysates, Lane 3: rat PC-12 whole cell lysates, Lane 4: mouse NIH/3T3 whole cell 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-DBF4 antigen affinity purified polyclonal antibody (Catalog # orb654419) 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 # orb90503) with Tanon 5200 system. A specific band was detected for DBF4 at approximately 80 kDa. The expected band size for DBF4 is at 80 kDa.

IF analysis of DBF4 using anti-DBF4 antibody (orb654419) and anti-Beta Tubulin antibody (orb623835). DBF4 was detected in immunocytochemical section of A549 cell. Enzyme antigen retrieval was performed using IHC enzyme antigen retrieval reagent (orb90553) for 15 mins. The cells were blocked with 10% goat serum. And then incubated with 5 μg/mL rabbit anti-DBF4 Antibody (orb654419) and mouse anti-Beta Tubulin antibody (orb623835) overnight at 4°C. Cy3 Conjugated Goat Anti-Rabbit IgG (orb27705) and DyLight®488 Conjugated Goat Anti-Mouse IgG were used as secondary antibody at 1: 500 dilution and incubated for 30 minutes at 37°C. Visualize using a fluorescence microscope and filter sets appropriate for the label used.

Flow Cytometry analysis of Raji cells using anti-DBF4 antibody (orb654419). Overlay histogram showing Raji cells stained with orb654419 (Blue line). To facilitate intracellular staining, cells were fixed with 4% paraformaldehyde and permeabilized with permeabilization buffer. The cells were blocked with 10% normal goat serum. And then incubated with rabbit anti-DBF4 Antibody (orb654419, 1μg/1x10^6 cells) for 30 min at 20°C. DyLight®488 conjugated goat anti-rabbit IgG (5-10μg/1x10^6 cells) was used as secondary antibody for 30 minutes at 20°C. Isotype control antibody (Green line) was rabbit IgG (1μg/1x10^6) used under the same conditions. Unlabelled sample (Red line) was also used as a control.
