Scientific Data

Smad7 in Human Liver Cancer Tissue. Smad7 was detected in immersion fixed paraffin-embedded sections of human liver cancer tissue using 25 µg/mL Human/Mouse/Rat Smad7 Monoclonal Antibody (Catalog # MAB2029) overnight at 4 °C. Tissue was stained with the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue).

Detection of Human/Mouse/Rat Smad7 by Western Blot. Western blot shows lysates of H9 human cutaneous T lymphoma cell line, PT18 mouse mast/basophil cell line, and Rat-2 rat embryonic fibroblast cell line. PVDF membrane was probed with 1 µg/mL of Human/Mouse/Rat Smad7 Monoclonal Antibody (Catalog # MAB2029) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Smad7 at approximately 50 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.

Smad7 in Human Liver. Smad7 was detected in immersion fixed paraffin-embedded sections of human liver array using Human/Mouse/Rat Smad7 Monoclonal Antibody (Catalog # MAB2029) at 25 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Lower panel shows a lack of labeling if primary antibodies are omitted and tissue is stained only with secondary antibody followed by incubation with detection reagents.

Detection of Human Smad7 by Simple WesternTM. Simple Western lane view shows lysates ofSf21S. frugiperdainsect ovarian cell line transfected with human Smad7, loaded at 0.2 mg/mL. A specific band was detected for Smad7 at approximately 56 kDa (as indicated) using 10 µg/mL of Mouse Anti-Human/Mouse/Rat Smad7 Monoclonal Antibody (Catalog # MAB2029). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background: Smad7
Smads are a family of intracellular proteins that transmit transforming growth factor beta (TGF-beta ) superfamily signals from the cell surface to the nucleus. The Smad family is divided into three subclasses: receptor regulated Smads, (Smads 1, 2, 3, 5 and 8); the common partner, (Smad4) that functions via its interaction to the various Smads; and the inhibitory Smads, (Smads 6 and 7). Smad7, also known as Mothers Against Decapentaplegic homolog 7 (MADH7), inhibits selected pathways by binding directly to cell-surface receptors and preventing the activation-induced phosphorylation of other Smad subunits.
