Western blot - Human USP22 knockout HeLa cell line (AB264888)
False colour image of Western blot : Anti-USP22 antibody [EPR18945] staining at 1/2000 dilution shown in green; Mouse anti-GAPDH antibody [6C5] (ab8245) loading control staining at 1/20000 dilution shown in red. In Western blot ab195289 was shown to bind specifically to USP22. A band was observed at 59 kDa in wild-type HeLa cell lysates with no signal observed at this size in usp22 knockout cell line ab264888 (knockout cell lysate ab257789). To generate this image wild-type and usp22 knockout HeLa cell lysates were analysed. First samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in fluorescent western blot (TBS-based) blocking solution before incubation with primary antibodies overnight at 4°. 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 (IRDye® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216776) 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.

Biological function summary
Removal of ubiquitin by USP22 regulates gene expression by modulating histone modifications. USP22 acts as a part of the Spt-Ada-Gcn5 acetyltransferase (SAGA) complex which plays a significant role in transcriptional regulation. Through its deubiquitinating activity USP22 alters the ubiquitination status of histone proteins thereby impacting chromatin dynamics and gene transcription.
Pathways
USP22 takes part in critical pathways like the ubiquitin-proteasome system and chromosome structure modulation. Within these processes USP22 closely interacts with proteins such as SAGA complex members and histone H2B. Its activity within this system highlights roles in transcriptional control and cellular growth important for maintaining cellular homeostasis and regulating cell cycle progression.
