Anti-RAB39B Antibody

RAB39B research reagent. Targeting RAB39B, a small Ras-related GTPase linked to vesicular trafficking and increasingly studied in models of X-linked intellectual disability and Parkinson's disease, this rabbit polyclonal primary antibody from Antibodies.com is supplied unconjugated for flexible Western Blot detection in human and rat samples.

Format and formulation. The reagent ships as 100 µl of liquid at approximately 1 mg/ml in phosphate buffered saline (PBS) containing 15 mM sodium azide as a preservative, buffered to roughly pH 7.2. Affinity purification supports specific recognition of endogenous RAB39B on Western Blot membranes, and the unconjugated format lets end users pair the primary antibody with HRP, fluorescent, or biotinylated secondary reagents matched to their imaging or chemiluminescence workflow.

Handling notes. Short-term storage is at refrigerated temperatures, with aliquoting recommended for long-term storage below freezing and avoidance of repeated freeze-thaw cycles that degrade polyclonal preparations. Researchers are encouraged to titrate the antibody against their own sample matrix, since lysate preparation, transfer conditions, and detection chemistry all influence the working dilution needed for clean RAB39B bands in whole-cell lysates or tissue homogenates.
