Scientific Data

Detection of Human Smad4 by Western Blot. Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line, Jurkat human acute T cell leukemia cell line, and K562 human chronic myelogenous leukemia cell line. PVDF membrane was probed with 0.25 µg/mL of Goat Anti-Human Smad4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2097) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for Smad4 at approximately 60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Detection of Smad4-regulated Genes by Chromatin Immunoprecipitation. Jurkat human acute T cell leukemia cell line treated with 10 ng/mL Recombinant Human IL-12 (Catalog # 219-IL) overnight was fixed using formaldehyde, resuspended in lysis buffer, and sonicated to shear chromatin. Smad4/DNA complexes were immunoprecipitated using 5 µg Goat Anti-Human Smad4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2097) or control antibody (Catalog # AB-108-C) for 15 minutes in an ultrasonic bath, followed by Biotinylated Anti-Goat IgG Secondary Antibody (Catalog # BAF109). Immunocomplexes were captured using 50 µL of MagCellect Streptavidin Ferrofluid (Catalog # MAG999) and DNA was purified using chelating resin solution. Thep21promoter was detected by standard PCR.

Smad4 in Human PBMCs. Smad4 was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) using Goat Anti-Human Smad4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2097) at 15 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 cytoplasm.

Background: Smad4
Smads are a family of intracellular proteins that transmit transforming growth factor beta (TGF-beta ) superfamily signals from the cell surface to the nucleus. Upon signal-induced phosphorylation, Smad subunits associate with the common-mediator subunit, Smad4. This heteromeric complex then translocates into the nucleus to exert transcriptional comodulator activity.
