Intracellular Staining by Flow Cytometry View Larger

Detection of p21/Cip1/CDKN1A in MCF‑7 Human Cell Line by Flow Cytometry. MCF‑7 human breast cancer cell line either treated with 1 μM camptothecin (CPT) for 16 hours (filled histogram) or untreated (open histogram) was stained with Alexa Fluor® 405‑conjugated Mouse Anti-Human p21/CIP1/CDKN1A Monoclonal Antibody (Catalog # IC1047V). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (Catalog # FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (Catalog # FC005).

Preparation and Storage

Background: p21/CIP1/CDKN1A

p21^CIP1, also called CIP1 (CDK-interacting protein 1) and CDKN1A, is a 21 kDa Cyclin/Cyclin-dependent kinase (Cdk) inhibitor that blocks cell cycle progression from G₁ to S phase in the cell cycle. Because p21 is a transcriptional target of the p53 tumor suppressor, p21 expression increases in cells that contain stabilized p53 due to genotoxic stress exposure.
