Flow Cytometry analysis of CACO-2 cells using anti-PTGS2 antibody (orb623891). Overlay histogram showing CACO-2 cells stained with orb623891 (Blue line). The cells were blocked with 10% normal goat serum. And then incubated with rabbit anti-PTGS2 Antibody (orb623891, 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.

Flow Cytometry analysis of HEPA1-6 cells using anti-PTGS2 antibody (orb623891). Overlay histogram showing HEPA1-6 cells stained with orb623891 (Blue line). The cells were blocked with 10% normal goat serum. And then incubated with rabbit anti-PTGS2 Antibody (orb623891, 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.

Western blot analysis of PTGS2 using anti-PTGS2 antibody (orb623891). 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: mouse RAW264.7 (-LPS) whole cell lysates, Lane 3: mouse RAW264.7 (+LPS) 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-PTGS2 antigen affinity purified polyclonal antibody (Catalog # orb623891) at 0.25 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 PTGS2 at approximately 75 kDa. The expected band size for PTGS2 is at 69 kDa.
