Glutamine Synthetase Antibody

Overview

Glutamine Synthetase Antibody is a research-use antibody directed against GLUTAMINE SYNTHETASE. It is supplied for use in common immunoassay contexts such as IHC-P, WB (RUO).

Key elements and design rationale

• Target: GLUTAMINE SYNTHETASE.
• Description (provided): The protein encoded by the GLUL gene belongs to the glutamine synthetase family.
• Antibody type: Rabbit, clone CCH-7, Rabbit IgG.
• Format: Purified; Affinity purified.
• Reported/predicted localization: Cytoplasmic.
• Species reactivity: tested: Human.
• Immunogen (if provided): A synthetic peptide specific to human Glutamine Synthetase / GLUL was used as the immunogen for the Glutamine Synthetase antibody..

The information above helps you match the antibody format to your assay context, interpret species-dependent differences, and anticipate how epitope context (isoforms, PTMs, or conformational state) may influence signal.

Biological background

The protein encoded by the GLUL gene belongs to the glutamine synthetase family. It catalyzes the synthesis of glutamine from glutamate and ammonia in an ATP-dependent reaction. This protein plays a role in ammonia and glutamate detoxification, acid-base homeostasis, cell signaling, and cell proliferation. Glutamine is an abundant amino acid, and is important to the biosynthesis of several amino acids, pyrimidines, and purines. Mutations in this gene are associated with congenital glutamine deficiency, and overexpression of this gene was observed in some primary liver cancer samples. [RefSeq]

Research relevance and current trends

• Context-dependent expression studies: researchers often examine GLUTAMINE SYNTHETASE abundance and localization across perturbations (genetic, pharmacologic, or environmental) to connect phenotype to molecular changes.
• Reagent reproducibility: there is growing emphasis on antibody specificity checks using orthogonal approaches (e.g., genetic perturbation or independent antibodies) and transparent reporting of clone/lot information.
• Multi-modal datasets: antibody-based readouts are increasingly combined with transcriptomics and imaging to relate protein-level measurements to cell-state transitions.

Common research applications

• Immunohistochemistry for spatial mapping of target expression across tissues and cell types.
• Western blotting (immunoblot) for relative detection of target protein abundance and apparent molecular weight.

When comparing conditions, interpret changes in signal in the context of sample composition, expected localization, and any known isoform complexity for the target.

Notes for experimental interpretation

• Isoforms and PTMs: alternative splicing or post-translational modifications can change epitope accessibility and apparent molecular weight; interpret bands/signals accordingly.
• Cross-reactivity and matrix effects: background binding can vary by sample type, species, and blocking/detection chemistries; include appropriate negative controls.
• Control concepts: where feasible, use genetic perturbation (KO/KD/overexpression), orthogonal assays, or independent antibodies to support specificity claims.

Antibody considerations: Polyclonal reagents may recognize multiple epitopes and can increase sensitivity but may show broader binding profiles, while monoclonal clones provide a single-epitope readout that can improve consistency across experiments. If a conjugate is listed, the antibody supports more direct detection workflows; otherwise, it is typically used with a compatible secondary antibody.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
