p16 (also known as p16INK4a, cyclin-dependent kinase inhibitor 2A, CDKN2A, multiple tumor suppressor 1 and numerous other synonyms), is a protein that slows cell division by slowing the progression of the cell cycle from the G1 phase to the S phase, thereby acting as a tumor suppressor. p16 can be used as a biomarker to improve the histological diagnostic accuracy of grade 3 cervical intraepithelial neoplasia (CIN). p16 is also implicated in the prevention of melanoma, oropharyngeal squamous cell carcinoma, cervical cancer, vulvar cancer and esophageal cancer.
ICC shows positive staining in HeLa cells. Anti- p16 (Alexa Fluor® 555 Conjugate) antibody was used at 1/2000 dilution (Red) and incubated overnight at 4°C. The cells were fixed with 4% PFA and permeabilized with 0.1% PBS-Triton X-100. Nuclei were counterstained with DAPI (Blue).
Negative control：ICC shows negative staining in MCF7 cells. Anti- p16 (Alexa Fluor® 555 Conjugate) antibody was used at 1/2000 dilution and incubated overnight at 4°C. The cells were fixed with 4% PFA and permeabilized with 0.1% PBS-Triton X-100. Nuclei were counterstained with DAPI (Blue).
IF shows positive staining in paraffin-embedded Human cervical squamous cell carcinoma. Anti- p16 (Alexa Fluor® 555 Conjugate) antibody was used at 1/1000 dilution (Red) and incubated overnight at 4°C. Counterstained with DAPI (Blue). Heat mediated antigen retrieval with EDTA buffer pH9.0 was performed before commencing with IF staining protocol.
