E2F‑1 in Human Placenta. E2F‑1 was detected in immersion fixed paraffin-embedded sections of human placenta using 5 µg/mL Sheep Anti-Human E2F‑1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4825) overnight at 4 °C. Tissue was stained with the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue).

Detection of Human E2F‑1 by Western Blot. Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line and human skin tissue. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human E2F-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4825) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for E2F-1 at approximately 60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Background: E2F-1

E2F-1 (adenovirus E2 gene promoter region binding factor 1; also retinoblastoma [RB]-binding protein 3/RBP3) is a 57 - 60 kDa nuclear member of the E2F/DP family of transcription factors. It has a dual function, mediating both cell proliferation and apoptosis in a context-dependent manner. Human E2F-1 is 437 amino acids (aa) in length. It contains a cyclin A: CDK2 binding site (aa 67 - 108), a DNA-binding region (aa 110 - 194), and an RB protein binding motif (aa 409 - 426) that, when engaged, inactivates E2F-1. There is one potential in-frame 23 aa substitution for aa 89 - 111. Over aa 264 - 437, human E2F-1 shows 89% and 80% aa identity to canine and mouse E2F-1, respectively.
