Scientific Data Images for Human Smad3 Antibody

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

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).

Detection of Smad3 antibody in PC-3 Human Cell Line antibody by Flow Cytometry.

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

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.
