Product Overview
This rabbit polyclonal antibody targets ras-related protein R-Ras (gene RRAS) in human samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 23.5 kDa, and the supplier reports an observed band at about 23 kDa.
R-Ras (RRAS) is a Ras-family small GTPase that shares effectors with classic Ras but has distinct roles. It promotes integrin activation and cell adhesion, influences the actin cytoskeleton and MAPK signaling, and has been studied in vascular stability and neuronal axon outgrowth.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human) |
|---|---|
| Flow cytometry (fixed cells) | 1–3 µg/1x1×106 cells (Human) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human A549 cells, human HeLa cells, human PC-3 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 RRAS fragment (Glu95–Gln194), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places ras-related protein R-Ras in the cell membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
