Western blot - Human RB1 knockout A549 cell line (AB286470)
Western blot : Anti-RB1 antibody (ab226979) staining at 1/1500 dilution, shown in green; Mouse anti-Alpha Tubulin [DM1A] (ab7291) loading control staining at 1/20000 dilution, shown in magenta. In Western blot, ab226979 was shown to bind specifically to RB1. A band was observed at 105 kDa in wild-type A549 cell lysates with no signal observed at this size in RB1 knockout cell line. To generate this image, wild-type and RB1 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 5 % 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
Retinoblastoma protein influences cellular proliferation differentiation and apoptosis. It acts within a larger protein complex modulating various cellular responses. When functional Rb halts uncontrolled cell division important for maintaining normal tissue homeostasis. In its phosphorylated state known as phospho-Rb or phospho-Rb E182 it loses its regulatory capabilities which can lead to unrestrained cell cycle progression.
Pathways
Several involve the retinoblastoma protein. One key pathway is the p53 pathway which Rb interacts with to influence cellular outcomes like cell-cycle arrest and apoptosis. Rb cooperates with proteins like p21 to implement these processes. Additionally it is involved in the cyclin D-dependent kinase 4 (CDK4) pathway which modulates its phosphorylation state influencing binding interactions and cell cycle control.
