Accession # P14921
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Detection of Human, Mouse, and Rat Ets-1 by Western Blot. Western blot shows lysates of Jurkat human acute T cell leukemia cell line, human thymus tissue, mouse thymus tissue, and rat CD4+T cells. PVDF membrane was probed with 0.5 µg/mL of Sheep Anti-Human/Mouse/Rat Ets-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7284) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Ets-1 at approximately 54 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Ets‑1 in Human Ovary. Ets-1 was detected in immersion fixed paraffin-embedded sections of human ovary using Sheep Anti-Human/Mouse/Rat Ets-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7284) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Sheep IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC006). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to plasma membrane in epithelial cells.

Ets-1 (E26 Transformation-Specific 1; also p54 and c-ets1) is a 52-54 kDa member of the ETS family of proteins. It is found in multiple cell types, and serves as a transcriptional regulator (generally activator) of multiple target genes, including prolactin, the transferrin receptor, and Cyclin E. By upregulating Cyclin E and CDK2 genes, it promotes cell-cycle progression. Ets‑1 forms complexes with both transcriptional activators (AP-1 and GHF-1) and repressors (MafB and Daxx). Human Ets‑1 is 441 amino acids (aa) in length. It contains one PNT domain (aa 51-136) that binds ERK2, and a DNA-binding ETS domain (aa 335-415). There are two SUMOylation sites, plus four utilized phosphorylation and acetylated lysine sites. At least four potential isoform variants are reported. One shows a deletion of aa 244-330 (termed isoform 1B), a second shows a deletion of aa 262-331, a third contains a deletion of aa 28-244, and a fourth possesses an 11 aa substitution for aa 262-441. Over aa 127-230, human Ets‑1 shares 95% aa identity with mouse Ets‑1.
