Product Overview
This rabbit polyclonal antibody detects ras-related protein Rab-9A (gene RAB9A) in human, mouse and rat samples and is validated for Western blot, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 22.8 kDa, and the supplier reports an observed band at about 23 kDa.
Rab9A (RAB9A) is a Rab GTPase on late endosomes that controls retrograde transport of cargo, such as mannose 6-phosphate receptors, back to the trans-Golgi network. It uses dynein-linked effectors for this movement and also contributes to melanosome biogenesis.

Immunogen
Recombinant human Rab9/RAB9A fragment (Lys4–Asp171), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places ras-related protein Rab-9A in the cell membrane, endoplasmic reticulum membrane and Golgi apparatus membrane. 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).
