Western blot - Human ARRB2 (Beta Arrestin 2) knockout A549 cell line (AB277840)
Western blot : Anti-ARRB2 antibody [EPR25410-70] (ab314213) staining at 1/1000 dilution, shown in green; Mouse anti-GAPDH antibody [6C5] (ab8245) loading control staining at 1/20000 dilution, shown in magenta. In Western blot, ab314213 was shown to bind specifically to ARRB2. A band was observed at 45 kDa in wild-type A549 cell lysates with no signal observed at this size in ARRB2 knockout cell line. To generate this image, wild-type and ARRB2 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.

Western blot - Human ARRB2 (Beta Arrestin 2) knockout A549 cell line (AB277840)
Western blot : Anti-INPPL1 antibody [EPR10955] (ab166916) staining at 1/1000 dilution, shown in green; Mouse anti-CANX [CANX/1543] (ab238078) loading control staining at 1/20000 dilution, shown in magenta. In Western blot, ab166916 was shown to bind specifically to INPPL1. A band was observed at 120-150 kDa in wild-type A549 cell lysates with no signal observed at this size in INPPL1 knockout cell line. To generate this image, wild-type and INPPL1 knockout A549 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane.

Reactivity data
Product details
Although we aim to provide customers with a homozygous clone, feasibility will be dependent on the biology of the protein. Should only heterozygous edits be achieved, you will be notified of the outcome and be asked to confirm whether the cell line is acceptable. All clones will be accompanied with DNA sequencing data, and the mutation description.
Recommended control: Human wild-type A549 cell line (ab288558). Please note a wild-type cell line is not automatically included with a knockout cell line order, if required please add recommended wild-type cell line at no additional cost using the code WILDTYPE-TMTK1.
We will provide viable cells that proliferate on revival.

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
Beta-arrestin 2 plays an important role in mediating signal transduction pathways beyond GPCR desensitization including those involved in cell communication and cellular response regulation. Beta-arrestin 2 interacts with multiple signaling proteins to form complexes that facilitate signaling pathways notably influencing MAPK (Mitogen-Activated Protein Kinase) pathways. It provides a scaffold for downstream signaling molecules affecting cell signaling outcomes.
Pathways
Beta-arrestin 2 significantly participates in two important biological pathways: the MAPK pathway and the Wnt signaling pathway. Through these pathways beta-arrestin 2 interacts with signaling proteins such as ERK1/2 (Extracellular signal-Regulated Kinases) and dishevelled proteins. These interactions highlight beta-arrestin 2's ability to modulate signal strength and duration contributing to diverse cellular responses.
