Product Overview
This rabbit polyclonal antibody targets FERM domain-containing protein 6 (gene FRMD6) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 72.0 kDa, and the supplier reports an observed band at about 72 kDa.
FRMD6 (also called Willin) is a FERM domain-containing protein found at the cell cortex and cell junctions. It is regarded as an upstream regulator of the Hippo pathway, related to Drosophila Expanded, and is studied in cell polarity, growth control and cancer, although its function is not fully characterized.

| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human HeLa cells, human PC-3 cells, human PANC-1 cells, human Caco-2 cells, rat PC-12 cells, mouse Neuro-2a 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, 50 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): A431 cells.
Immunogen
Recombinant human FRMD6/Willin fragment (Met1–Glu95), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places FERM domain-containing protein 6 in the cytoplasm and cell membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
