Western blot - Human CYBA (Cytochrome b245 Light Chain/p22-phox) knockout HEK-293T cell line (AB266721)
False colour image of Western blot : Anti-CYBA antibody (ab191512) staining at 1 µg/ml shown in green; Mouse anti-Alpha Tubulin [DM1A] (ab7291) loading control staining at 1/20000 dilution shown in red. In Western blot ab191512 was shown to bind specifically to CYBA. A band was observed at 23 kDa in wild-type HEK-293T cell lysates with no signal observed at this size in CYBA knockout cell line ab266721 (knockout cell lysate ab257405). To generate this image wild-type and CYBA knockout HEK-293T 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
The p22-phox serves as a core component of the NADPH oxidase complex which is integral to cellular responses to infection and stress. It operates in conjunction with other cytosolic subunits to produce reactive oxygen species that help in microbial destruction and signal transduction. The presence of p22-phox is essential for proper enzyme assembly and function as its interaction with gp91-phox establishes the electron transport chain required for oxidase activity.
Pathways
P22-phox contributes to the oxidative burst pathway a critical mechanism in innate immunity. In this pathway its interactions with proteins like Rac a small GTPase facilitate the activation and membrane association of the oxidase complex. Additionally p22-phox has involvement in inflammatory pathways by aiding in the release of signaling molecules that trigger inflammatory responses. This protein cooperates with components of the MAPK signaling pathway acting as a mediator in signal transduction events that dictate cellular responses to external stimuli.
