Product Overview
This rabbit polyclonal antibody targets endogenous retrovirus group 3 member 1 Env polyprotein (gene ERV3-1) in human samples and is validated for Western blot. The predicted molecular weight is 67.9 kDa, and the supplier reports an observed band at about 68 kDa.
ERV3-1 encodes the envelope protein of an endogenous retrovirus that integrated into the primate genome long ago. Unlike syncytin-1, it has lost the ability to fuse membranes, but it is expressed in the placenta and other tissues, where it may influence cell growth and differentiation.

|---|
Samples with a confirmed band (WB): human THP-1 cells, human K562 cells, human HepG2 cells, human U251 cells, human MCF-7 cells, human RT4 cells, human Jurkat cells, human SiHa 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 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Immunogen
Synthetic peptide from the C-terminal region of human ERV31.
Reactivity Notes
The supplier lists reactivity with human. UniProt places endogenous retrovirus group 3 member 1 Env polyprotein in the virion. Tissue expression noted by UniProt (human): Expressed at higher level in adrenal, sebaceous glands and placenta. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
