Scientific Data Images for Human HES-1 Antibody

Detection of Human HES‑1 by Western Blot.

Western blot shows lysates of HEK293 human embryonic kidney cell line either mock transfected or transfected with human HES-1. PVDF Membrane was probed with 1 µg/mL of Goat Anti-Human HES-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3317) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for HES-1 at approximately 35 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

HES-1 in Human Ovarian Cancer Tissue.

HES-1 was detected in immersion fixed paraffin-embedded sections of human ovarian cancer tissue using Goat Anti-Human HES-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3317) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific labeling was localized to the cytoplasm of cancer cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Background: HES-1

HES-1 is a transcriptional repressor that is a target of notch signaling. It contains a basic helix-loop-helix (bHLH) DNA-binding domain, an Orange domain and a C‑terminal tetrapeptide WRPW motif that binds to the Groucho (Gro)/TLE/Grg family of corepressors. HES-1 can form both homo- and heterodimers with other HES family members. Dimerization is mediated through both the bHLH and the downstream Orange domain. Over the sequence used for immunization, human HES-1 shares 97% and 98% amino acid sequence identity with mouse and rat HES-1, respectively.
