Anti-GLUL Antibody

Manufactured by Antibodies.com, this affinity-purified reagent is supplied as a 50 µL volume of rabbit polyclonal antiserum raised against recombinant full-length human GLUL (glutamate-ammonia ligase, also known as glutamine synthetase). The unconjugated antibody is formulated at 1 mg/mL in PBS containing 0.1% sodium azide and 50% glycerol, providing a ready-to-use stock suitable for standard immunodetection workflows. Validated applications include Western blot (WB), immunohistochemistry (IHC), and immunofluorescence (IF), and the antibody has been confirmed to cross-react with Human, Mouse, and Rat samples. Endogenous levels of the approximately 49 kDa GLUL protein are detected with high specificity, and the preparation is purified by affinity chromatography using an epitope-specific immunogen to a purity greater than 95% by SDS-PAGE. The polyclonal format offers broader epitope coverage than monoclonal alternatives, which is particularly valuable when probing for glutamine synthetase across different tissues and species. For short-term storage, the glycerol-containing buffer allows the reagent to remain aliquoted at –20 °C with minimal freeze–thaw loss, while long-term storage at –80 °C is recommended. Suitable for research use only, this reagent is a reliable choice for studies in neuroscience, liver biology, and cell metabolism where glutamine synthetase expression is of interest.
