Anti-GLUL Antibody

This unconjugated rabbit polyclonal antibody recognizes glutamate-ammonia ligase (GLUL), the enzyme commonly referred to as glutamine synthetase. Produced in rabbits and affinity-purified at Antibodies.com, it is supplied at approximately 1 mg/ml in phosphate buffered saline (PBS) containing 0.05% sodium azide at pH 7.2, validated for Western blot detection of the human, mouse, and rat protein.

Researchers studying astrocyte biology, hepatic nitrogen metabolism, and glutamine homeostasis rely on GLUL as both a functional readout and a cell-type marker. The reagent supports investigation of glial scarring in injury models, hepatocellular differentiation, and tumor microenvironments where glutamine dependence drives proliferation. Each vial is provided in a 100 µL format; sodium azide at 0.05% acts as a preservative, and aliquoting upon first use is recommended to limit repeated freeze-thaw cycles. Refrigerate working aliquots; store frozen at -20 degrees C for longer-term stock.
