Western blot - Human PTGS2 (COX2 / Cyclooxygenase 2) knockout A549 cell line (AB280802)
False colour image of Western blot : Anti-COX2 / Cyclooxygenase 2 antibody [EPR18377-106] - N-terminal staining at 1/1000 dilution, shown in green; Mouse anti-GAPDH antibody [6C5] (ab8245) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab188183 was shown to bind specifically to COX2 / Cyclooxygenase 2. A band was observed at 74-76 kDa in wild-type A549 cell lysates with no signal observed at this size in PTGS2 knockout cell line ab280802 (knockout cell lysate ab283825). Band at 70 kDa in both wild-type and knockout samples is non-specific but exact protein is not determined. To generate this image, wild-type and PTGS2 knockout A549 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.

Handling procedures
Initial handling guidelines
Upon arrival, the vial should be stored in liquid nitrogen vapor phase and not at -80°C. Storage at -80°C may result in loss of viability.
1. Thaw the vial in 37°C water bath for approximately 1-2 minutes.
2. Transfer the cell suspension (0.8 mL) to a 15 mL/50 mL conical sterile polypropylene centrifuge tube containing 8.4 mL pre-warmed culture medium, wash vial with an additional 0.8 mL culture medium (total volume 10 mL) to collect remaining cells, and centrifuge at 201 x g (rcf) for 5 minutes at room temperature. 10 mL represents minimum recommended dilution. 20 mL represents maximum recommended dilution.
3. Resuspend the cell pellet in 5 mL pre-warmed culture medium and count using a haemocytometer or alternative cell counting method seed all remaining cells into a T25.
4. Incubate the culture at 37°C incubator with 5% CO2. Check the culture one day after revival and continue to check until 80% confluent. Media change can be given if needed.
5. Once confluent passage into an appropriate flask at a density of 2x104 cells/cm2. Seeding density is given as a guide only and should be scaled to align with individual lab schedules. Cultures should be monitored daily.
Subculture guidelines
- All seeding densities should be based on cell counts gained by established methods.
- A guide seeding density of 2x104 cells/cm2 is recommended.
- Cells should be passaged when they have achieved 80-90% confluence.
- Do not allow the cell density to exceed 7x104 cells/cm2.
Culture medium
F-12K + 10% FBS
Cryopreservation medium
Cell Freezing Medium-DMSO Serum free media, contains 8.7% DMSO in MEM supplemented with methyl cellulose.

Biological function summary
COX2 plays a significant role in the inflammatory response and is part of the complex process of synthesizing prostaglandins. These compounds mediate inflammation and pain making COX2 an important target for understanding these processes. COX2 is not ubiquitously expressed but rather is induced in activated macrophages and other cells during inflammatory conditions. Its function is also important for normal physiological processes like ovulation and implantation.
Pathways
COX2 is essential in the prostaglandin biosynthesis pathway connecting it to the arachidonic acid metabolism pathway. Cyclooxygenase 2 works with phospholipase A2 which releases arachidonic acid from the phospholipid membrane. COX2 then converts this acid to prostaglandin H2 a precursor for other prostaglandins. COX1 the other isoform of cyclooxygenase is closely related to COX2 and while they have different expression patterns they share some functional similarities in these pathways.
