Product Overview
This rabbit polyclonal antibody detects TGF-beta receptor type-1 (gene TGFBR1) in human, mouse and rat samples and is validated for Western blot. The predicted molecular weight is 56.0 kDa, and the supplier reports an observed band at about 56 kDa.
TGF-β receptor type 1 (TGFBR1, also called ALK5) is a transmembrane serine/threonine kinase. When TGF-β binds the type II receptor, TGFBR1 is recruited and phosphorylated, and it then phosphorylates SMAD2 and SMAD3 to relay signals for growth control, matrix production and immune regulation; it is also a common drug target in fibrosis and cancer studies.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Human, Mouse, Rat) |
|---|
Samples with a confirmed band (WB): rat cardiac muscle tissue, mouse liver tissue, HeLa cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Immunogen
Synthetic peptide from the N-terminal region of human TGFBR1. The peptide sequence is conserved in mouse and rat.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places TGF-beta receptor type-1 in the cell membrane, cell junction, cell surface and membrane raft. Tissue expression noted by UniProt (human): Found in all tissues examined, most abundant in placenta and least abundant in brain and heart. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
