Western blot - Human PER2 knockout A549 cell line (AB301148)
Western blot : Anti-PER2 antibody (ab227727) staining at 1/2000 dilution, shown in green; Mouse anti-Alpha Tubulin [DM1A] (ab7291) loading control staining at 1/20000 dilution, shown in magenta. In Western blot, ab227727 was shown to bind specifically to PER2. A band was observed at 171 kDa in wild-type A549 cell lysates with no signal observed at this size in PER2 knockout cell line. To generate this image, wild-type and PER2 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.

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.
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.

Biological function summary
The PER2 protein plays an important role in the regulation of genes that control the body's circadian rhythms. It participates in the negative feedback loop of the circadian clock where it is part of a complex with other proteins including CRY1 and CRY2. This complex inhibits its own transcription by repressing the activity of CLOCK and BMAL1 which are core circadian transcription factors. This process results in the oscillations that define circadian rhythms affecting sleep-wake cycles hormone release and various metabolic processes.
Pathways
PER2 is integral to the circadian rhythm pathway and is involved in the regulation of several physiological processes. PER2 along with other proteins like PER1 interacts with the CLOCK-BMAL1 complex which is important in setting and maintaining the circadian rhythms. The interplay of these proteins governs the transcriptional-translational feedback loops that are the foundation of circadian regulation. This pathway is critical for synchronizing the internal clock with the external environment ensuring that biological processes occur at the appropriate times.
