Scientific Data

Immunohistochemistry Smad3 antibody in Human Pancreatic Cancer Tissue by Immunohistochemistry (IHC-P). View Larger

Smad3 in Human Pancreatic Cancer Tissue. Smad3 was detected in immersion fixed paraffin-embedded sections of human pancreatic cancer tissue using 15 µg/mL Rat Anti-Human Smad3 Monoclonal Antibody (Catalog # MAB4038) overnight at 4 °C. Before incubation with the primary antibody tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained with the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue).

Intracellular Staining by Flow Cytometry Detection of Smad3 antibody in PC‑3 Human Cell Line antibody by Flow Cytometry. View Larger

Detection of Smad3 in PC‑3 Human Cell Line by Flow Cytometry. PC‑3 human prostate cancer cell line was stained with Rat Anti-Human Smad3 Monoclonal Antibody (Catalog # MAB4038, filled histogram) or isotype control antibody (Catalog # MAB005, open histogram), followed by Allophycocyanin-conjugated Anti-Rat IgG F(ab')2Secondary Antibody (Catalog # F0113). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with methanol.

Immunocytochemistry Smad3 antibody in MDA-MB-231 Human Cell Line by Immunocytochemistry (ICC). View Larger

Smad3 in MDA‑MB‑231 Human Cell Line. Smad3 was detected in immersion fixed MDA-MB-231 human breast cancer cell line using Rat Anti-Human Smad3 Monoclonal Antibody (Catalog # MAB4038) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rat IgG Secondary Antibody (red; Catalog # NL013) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm and nuclei. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Background: Smad3

Smad3 is phosphorylated in cells stimulated with TGF-beta, complexes with Smad4, and translocates to the nucleus to upregulate gene transcription. Smad3 is critical for signaling fibrosis and wound healing.
