Anti-GLUL / Glutamate-ammonia ligase, clone MSVA-750M

Antibody in 1X PBS with 0.05% BSA, 0.05% sodium azide. Glutamate-ammonia ligase, encoded by the GLUL gene, is widely known as Glutamine synthetase and functions as a key cytoplasmic enzyme involved in nitrogen metabolism and cellular glutamine production. GLUL Antibody for IHC MSVA-750M is designed for immunohistochemical detection of glutamine synthetase in formalin-fixed, paraffin-embedded tissue sections. Because GLUL expression follows highly characteristic tissue distribution patterns, immunohistochemistry provides a powerful method for visualizing cellular localization and evaluating tissue-specific metabolic organization.In immunohistochemical studies of normal tissues, glutamine synthetase shows distinct cytoplasmic staining patterns that reflect specialized metabolic zones. In the liver, GLUL is strongly expressed in pericentral hepatocytes surrounding central veins, producing a sharply defined zonal staining pattern that is frequently used to assess hepatic architecture and metabolic compartmentalization. In the central nervous system, immunohistochemistry reveals GLUL expression primarily in astrocytes, where cytoplasmic staining outlines astrocytic cell bodies and processes within the neuropil. This distribution corresponds to the enzyme's role in the glutamate-glutamine cycle and regulation of neurotransmitter metabolism.Immunohistochemical detection of GLUL is also observed in kidney, gastrointestinal epithelium, and selected epithelial and glandular tissues depending on metabolic demand. Cytoplasmic staining typically appears diffuse to finely granular within positive cells, reflecting the known intracellular localization of glutamine synthetase. These patterns allow investigators to evaluate both tissue distribution and cell-type specific expression when examining normal physiology or disease-associated alterations.GLUL immunohistochemistry is frequently used in tumor biology research. Altered glutamine synthetase expression has been reported in hepatocellular carcinoma and other malignancies, where IHC staining can reveal changes in metabolic pathway activation and cellular differentiation. The ability to visualize GLUL-positive cells within tissue architecture makes immunohistochemistry particularly valuable for correlating metabolic enzyme expression with histologic features.As a monoclonal reagent optimized for tissue staining, GLUL Antibody for IHC MSVA-750M supports clear cytoplasmic detection of glutamine synthetase in formalin-fixed tissue sections. This antibody is well suited for studies examining tissue distribution, metabolic zonation, and tumor-associated changes in glutamine metabolism through immunohistochemical analysis.This antibody is also part of a broader collection of IHC antibodies validated by tissue microarray analysis, supporting consistent staining across normal and cancer tissues.
