Product Overview
This rabbit polyclonal antibody recognizes GTPase HRas in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF and immunoprecipitation. The predicted molecular weight is 21.3 kDa, and the supplier reports an observed band at about 18 kDa.
HRAS is one of the three classic Ras small GTPases. It cycles between an active GTP-bound and an inactive GDP-bound state and passes signals from growth factor receptors to the RAF-MEK-ERK and PI3K pathways that control proliferation and survival. Activating HRAS mutations occur in some tumors and cause Costello syndrome.

Samples with a confirmed band (WB): human 293T cells, human SH-SY5Y cells, human PC-3 cells, human MCF-7 cells, rat kidney tissue, rat C6 cells, mouse kidney tissue, mouse NIH3T3 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 12% 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 confirmed staining (IHC): human cerebral cortex tissue, human stomach tissue, mouse brain tissue, rat brain tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Samples with confirmed staining (ICC/IF): A549 cells.
Samples with a confirmed result (IP): MCF-7 cells.
Immunogen
Synthetic peptide from the C-terminal region of human GTPase HRAS. The peptide sequence is conserved in mouse and rat.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places GTPase HRas in the cell membrane, Golgi apparatus and Golgi apparatus membrane. Tissue expression noted by UniProt (human): Widely expressed. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
