Product Overview
Clone GHA-18 is a rabbit monoclonal antibody that recognizes ras-related protein Rab-7a (gene RAB7A) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF and flow cytometry. The predicted molecular weight is 23.5 kDa, and the supplier reports an observed band at about 23 kDa.
Rab7 (RAB7A) is the main Rab GTPase of late endosomes and lysosomes. Through effectors such as RILP and the HOPS complex it drives endosome maturation, microtubule-based positioning and fusion with lysosomes, and it is also needed for autophagosome–lysosome fusion, making it a standard late endosome marker.

Samples with a confirmed band (WB): human A375 cells, human HT1080 cells, human U87 cells, human HEL cells, rat brain tissue, rat L6 cells, mouse brain tissue, mouse C2C12 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 1:1000 overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human colon tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Samples with confirmed staining (ICC/IF): HeLa cells.
Immunogen
Synthetic peptide based on the sequence of human RAB7.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places ras-related protein Rab-7a in the cytoplasmic vesicle, late endosome membrane and lysosome 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).
