Background
SMAD (mothers against decapentaplegic homologs) molecules are the core components in TGF-β signaling pathway. TGF-β binding to its receptor induces phosphorylation and activation of receptor-regulated SMADs (R-SMADs), SMAD2 and SMAD3, which subsequently associate with their partner SMAD4 and translocate from cytoplasm to nucleus. Formation of R-SMAD–SMAD4 complexes is essential in signaling of most TGF-β family members.

Western Blot
FC
Flow cytometric analysis of HT-29 (Human colorectal adenocarcinoma epithelial cell, left) / HepG2 (Human hepatocellular carcinoma epithelial cell, right) cells labelling SMAD4 antibody at 1/500 dilution (0.1 μg)/ (red) compared with a Rabbit monoclonal IgG (Black) isotype control and an unlabelled control (cells without incubation with primary antibody and secondary antibody) (Blue). Goat Anti-Rabbit IgG Alexa Fluor® 488 was used as the secondary antibody. Negative control: HT-29 cells
Immunohistochemistry
IHC shows positive staining in paraffin-embedded human colon cancer. Anti-SMAD4 antibody was used at 1/100 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.

IHC shows positive staining in paraffin-embedded human lung squamous cell carcinoma. Anti-SMAD4 antibody was used at 1/100 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
IHC shows positive staining in paraffin-embedded human pancreatic cancer (Loss of SMAD4 expression in tumors but nuclear expression in stromal cells). Anti-SMAD4 antibody was used at 1/100 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
IHC shows positive staining in paraffin-embedded human pancreatic cancer (Loss of SMAD4 expression in tumors but expression in stromal and paracancerous cells). Anti-SMAD4 antibody was used at 1/100 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
Immunocytochemistry
ICC shows positive staining in HepG2 cells. Anti-SMAD4 antibody was used at 1/100 dilution (Green) and incubated overnight at 4°C. Goat polyclonal Antibody to Rabbit IgG - H&L (Alexa Fluor® 488) was used as secondary antibody at 1/1000 dilution. The cells were fixed with 4% PFA and permeabilized with 0.1% PBS-Triton X-100. Nuclei were counterstained with DAPI (Blue).
