Product Overview
Clone HAF-19 is a rabbit monoclonal antibody that recognizes SMAD family member 5 (gene SMAD5) phosphorylated at Ser463/Ser465/Ser467 in human, mouse and rat samples and is validated for Western blot. The predicted molecular weight is 52.3 kDa, and the supplier reports an observed band at about 52 kDa.
SMAD5 is a receptor-regulated SMAD in the BMP pathway. When phosphorylated by BMP type I receptors it binds SMAD4 and regulates gene transcription in development, cell differentiation and angiogenesis; the unphosphorylated protein has also been linked to regulation of glycolysis in the cytoplasm.

Samples with a confirmed band (WB): human HeLa cells, human 293T cells, human Caco-2 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 10% SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 1:500 overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Immunogen
Synthetic phosphopeptide based on human Phospho-Smad1/5/9.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places SMAD family member 5 in the cytoplasm, nucleus and mitochondrion. Tissue expression noted by UniProt (human): Ubiquitous. The samples tested by the supplier (listed above) are a practical starting point for positive controls. Because the antibody is phospho-specific, signal depends on the phosphorylation state of the sample; a phosphatase-treated lysate is a useful negative control.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
