Product Overview
This rabbit polyclonal antibody targets phospholemman (gene FXYD1) in human, mouse and rat samples and is validated for IHC and Western blot. The predicted molecular weight is 10.4 kDa, and the supplier reports an observed band at about 10 kDa.
Phospholemman (FXYD1) is a small single-pass membrane protein of the FXYD family that regulates the Na+/K+-ATPase, particularly in heart and skeletal muscle. When unphosphorylated it inhibits the pump, and phosphorylation by protein kinases A and C relieves this inhibition, so it is studied in cardiac ion homeostasis and contractility.

Validated Applications
| IHC (paraffin sections) | 0.5–1 µg/mL (Human, Mouse, Rat) |
|---|---|
| Western blot | 0.1–0.5 µg/mL (Human, Mouse, Rat) |
Samples with a confirmed band (WB): rat liver tissue, rat cardiac muscle tissue, mouse cardiac muscle tissue, HepG2 cells, HeLa cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE, 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.
Samples with confirmed staining (IHC): mouse cardiac muscle tissue, rat cardiac muscle tissue, human prostatic cancer tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Recombinant human FXYD1 fragment (Glu21–Arg92), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 86.1% and 87.5%, respectively.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places phospholemman in the cell membrane, apical cell membrane and membrane. Tissue expression noted by UniProt (human): Highest expression in skeletal muscle and heart. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
