Scientific Data Images for Human p21/CIP1/CDKN1A Antibody
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.
Detection of p21/CIP1/CDKN1A by Western Blot
Effect of the single agent and combination compound using RAPTA-T and olaparib on protein expression. (A) Whole-cell proteins were prepared from the cells treated with IC50 of the compound for 24 h. Cellular protein extracts were separated on a 6%, 8% and 12% SDS-PAGE gel, transferred onto nitrocellulose membrane, and immunoblotted with the primary antibodies. The protein loading of each sample was controlled by beta -actin expression. (B) The percentage of relative expression of protein was shown for each cell line. Experiments were performed in duplicate. Statistically significant differences from the untreated control are indicated by * p < 0.05.
