NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.
NOTE: Do not allow slides to dry at any time during this procedure.
For Citrate: Heat slides in a microwave submersed in 1X citrate unmasking solution until boiling is initiated; follow with 10 min at a sub-boiling temperature (95°-98°C). Cool slides on bench top for 30 min.

Protocol Id: 283
Human, Mouse, Rat
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala297 of human GLUL protein.
Glutamate-ammonia ligase (GLUL), also known as glutamine synthetase (GS), catalyzes the de novo synthesis of glutamine from glutamate and ammonia. GLUL is ubiquitously expressed with particularly high expression in the muscle, liver, and brain (1). GLUL expression is elevated in various cancers. Its expression is upregulated by oncogenic c-Myc (2). High expression of GLUL in breast cancer patients is associated with larger tumor size and high level of HER2 expression. It is a predictor of poor survival in patients with glioma and liver cancers (3-6).
