Product Overview
This rabbit polyclonal antibody recognizes selenoprotein N (gene SELENON) in human samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 65.8 kDa, and the supplier reports an observed band at about 66–70 kDa.
Selenoprotein N (SELENON, also SEPN1) is an endoplasmic reticulum selenoprotein that protects cells against oxidative stress. It keeps the calcium pump SERCA2 active by reducing oxidized cysteines and modulates ryanodine receptor activity, and SELENON mutations cause congenital myopathies with muscle weakness.

| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human A549 cells, human HepG2 cells, human 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.
Samples with a confirmed signal (flow cytometry): HEL cells.
Immunogen
Recombinant human SELENON fragment (His260–Pro590), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. Tissue expression noted by UniProt (human): Isoform 1 and isoform 2 are expressed in skeletal muscle, brain, lung and placenta. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
