• Target description: Glutamine synthetase (UniProt: P15104; also known as EC:6.3.1.2, GS, Glutamate--ammonia ligase, Palmitoyltransferase GLUL) is encoded by the GLUL (also known as GLNS) gene (Gene ID: 2752) in human. Glutamine synthetase (GS), a decameric enzyme composed of two pentamers, is a crucial enzyme that eliminates both toxic ammonia and neurotoxic glutamate by combining them to form glutamine that serves as a building block for the biosynthesis of several metabolites. Its active site is inserted in the interface between adjacent monomers, within the same pentameric ring. Independently of its glutamine synthetase activity, GS is also required for endothelial cell migration during vascular development. Three different types of GS have been described (GS1, II, and III). In mammals, GSII is the most common type. Its expression is observed in endothelial cells and it is mainly localized in the cytosol, with a fraction associated with the cell membrane. Its catalytic mechanism involves a two-phase reaction cycle. During phase 1, GS activates the reactants (ammonia and glutamate) with high efficiency, through NH4+ deprotonation by glutamic acid 305 and glutamate phosphorylation by ATP. Phase 2 is the rate limiting step and, in this phase, NH3 attacks the -glutamyl phosphate being concomitantly deprotonated by the leaving PO4 , forming the glutamine and HPO4 products. Mutations in GLUL gene is known to cause Congenital systemic glutamine deficiency (CSGD), a rare developmental disorder with severe brain malformation resulting in multi-organ failure and neonatal death. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

• Physical form: Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.
• Reconstitution: 30 µg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.
• Storage and Stability: Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
