Overlay histogram showing HeLa (Human epithelial cell line from cervix adenocarcinoma) cells stained with ab54210 (red line).

The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab54210, 1/50 dilution) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG2b [PLPV219] (ab91366, 2μg/1x106 cells) used under the same conditions.

Acquisition of >5,000 events was performed.

This antibody gave a positive signal in HeLa cells fixed with 4% paraformaldehyde/permeabilized in 0.1% PBS-Tween used under the same conditions.

Target Information

CDKN2A, also known as cyclin-dependent kinase inhibitor 2A, is a crucial tumor suppressor gene located on chromosome 9p211. It encodes two proteins, p16INK4a and p14ARF, both of which play significant roles in regulating the cell cycle. p16INK4a inhibits cyclin-dependent kinases 4 and 6 (CDK4 and CDK6), preventing the progression from the G1 to S phase of the cell cycle. This inhibition is vital for controlling cell proliferation and preventing tumor growth. Mutations or deletions in CDKN2A are frequently associated with various cancers, including melanoma, pancreatic cancer, and head and neck squamous cell carcinoma.

Target data

The protein expressed by the gene CDKN2A acts as a negative regulator of normal cell proliferation by strongly interacting with CDK4 and CDK6. This interaction inhibits the ability of CDK4 and CDK6 to interact with cyclins D and to phosphorylate the retinoblastoma protein. This supplementary information is collated from multiple sources and compiled automatically.
