Product Overview
This rabbit polyclonal antibody detects activin receptor type-2A (gene ACVR2A) in human samples and is validated for Western blot and ELISA. The predicted molecular weight is 57.8 kDa, and the supplier reports an observed band at about 58 kDa.
Activin receptor type-2A (ACVR2A) is a type II serine/threonine kinase receptor for activins, myostatin and other TGF-β family ligands. After ligand binding it phosphorylates type I receptors, which then activate SMAD proteins, and it is studied in reproduction, muscle growth and bone.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human) |
|---|---|
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human HepG2 cells, human RT4 cells, human SH-SY5Y cells, human 293T 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
Recombinant human ACVR2A fragment (Ala20–Asn138), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 98.3%.
Reactivity Notes
The supplier lists reactivity with human. UniProt places activin receptor type-2A in the cell membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
