| 背景 | p21CIP1, 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. |

Detection of Human p21/CIP1/CDKN1A by Western Blot. Western blot shows lysates of MCF‑7 human breast cancer cell line untreated (-) or treated (+) with 1 μM camptothecin (CPT) for 16 hours. PVDF membrane was probed with 0.5 µg/mL of Goat Anti-Human p21/CIP1/CDKN1A Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1047), followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for p21/CIP1/CDKN1A at approximately 21 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1. | |
p21/CIP1/CDKN1A in MCF‑7 Human Cell Line. p21/CIP1/CDKN1A was detected in immersion fixed MCF‑7 human breast cancer cell line treated with (left panel) or without (right panel) camptothecin using Goat Anti-Human p21/CIP1/CDKN1A Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1047) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to nuclei.

p21/CIP1/CDKN1A in Human Breast Cancer Tissue. p21/CIP1/CDKN1A was detected in immersion fixed paraffin-embedded sections of human breast cancer tissue using 1.7 µg/mL Goat Anti-Human p21/CIP1/CDKN1A Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1047) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

Detection of p21/CIP1/CDKN1A in MCF‑7 Human Cell Line by Flow Cytometry. MCF‑7 human breast cancer cell line was unstimulated (light orange filled histogram) or treated with 1 μM camphtothecin for 16 hours, then stained with Goat Anti-Human p21/CIP1/CDKN1A Antigen Affinity‑purified Polyclonal Antibody (Catalog # AF1047, dark orange filled histogram) or isotype control antibody (Catalog # AB-108-C, open histogram), followed by Allophycocyanin-conjugated Anti-Goat IgG Secondary Antibody (Catalog # F0108). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with methanol. | |
Detection of Human p21/CIP1/CDKN1A by Simple WesternTM. Simple Western lane view shows lysates of MCF‑7 human breast cancer cell line untreated (-) or treated (+) with 1 µM Camptothecin (CPT) for 16 hours, loaded at 0.2 mg/mL. A specific band was detected for p21/CIP1/CDKN1A at approximately 30 kDa (as indicated) using 5 µg/mL of Goat Anti-Human p21/CIP1/CDKN1A Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1047) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system. |
