Product Overview
This rabbit polyclonal antibody recognizes ral-GDS-related protein (gene RGL4) in human samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 52.3 kDa, and the supplier reports an observed band at about 52 kDa.
RGL4 (Ral-GDS-related protein) belongs to the Ral guanine nucleotide dissociation stimulator family, which activates Ral GTPases downstream of Ras; its specific function has not been fully characterized.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human) |
|---|---|
| Flow cytometry (fixed cells) | 1–3 µg/1×106 cells (Human) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human MOLT-4 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.
Samples with a confirmed signal (flow cytometry): SiHa cells.
Immunogen
Recombinant human RGL4 fragment (Arg37–Arg381), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places ral-GDS-related protein in the cytoplasmic vesicle. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
