Scientific Data Images for Glutamine Synthetase Antibody

Western Blot: Glutamine Synthetase Antibody [NB110-41404] - Analysis of glutamine synthase. 40ug of lysates from mouse (Lanes M), rat (Lane R), pig (Lane P), bovine (Lane B), or human (Lane Hu) retina were probed. A 42 kDa band was identified in lysates from retinas of all species.
Immunocytochemistry/Immunofluorescence: Glutamine Synthetase Antibody [NB110-41404] - Immunofluorescence using NB110-41404. Submitted via verified customer review.
Immunohistochemistry: Glutamine Synthetase Antibody [NB110-41404] - Localization of glutamine synthase in the retina. Paraffin sections of mouse (A, B), rat (C, D, G-I), or human (E, F) retina fixed in 4% paraformaldehyde were reacted with anti-glutamine synthase (red fluorescence staining in B, D, G, I, and brown immuno-peroxidase reaction. Nuclei in IF experiments (A-D) were stained with DAPI (cyan), and with nuclear fast red in E and F. At low magnification, anti-glutamine synthase reacted with a single population of cells extending from the ganglion cell layer through the inner nuclear layer. No signal was detected in controls either pre-incubated with 100ug/ml of the immunizing peptide (A) or with pre-immune serum (C, E). This finding was confirmed by co-localization (indicated by yellow in I) of glutamine synthase (red in G) with antoher marker of glutamine synthase (green in H).

Background: Glutamine Synthetase

Glutamine synthetase (GLUL) is an enzyme responsible for the de novo synthesis of glutamine (from glutamate and ammonia, wherein glutamate act as nitrogen donor/acceptor) and for production of gamma-aminobutyric acid/GABA (4-aminobutanoate). GLUL is expressed in a wide variety of human cells, such as astrocytes (marker protein), skeletal cells, adipocytes, hepatocytes and sperm. GLUL activity in vertebrate brain is generally high as it protects this ammonia-sensitive organ from harmful effects of ammonia and is involved in recycling of neurotransmitter glutamate also. GLUL is essential in maintaining cellular homeostasis and besides its involvement in ammonia detoxification, GLUL participates in maintaining amino acid/energy balance, cellular redox control, nucleotide biosynthesis and neurotransmitters regulation. Defects in GLUL are the cause of congenital systemic glutamine deficiency (CSGD) which is a rare developmental disorder with severe brain malformation resulting in multi-organ failure and neonatal death.

FAQs for Glutamine Synthetase Antibody

Showing  1 - 1 of 1 FAQ Showing All
  • Q: I'm looking for a primary antibody specific to the cytosolic isoform of glutamine synthetase.

    A: I see no evidence that glutamine synthetase has multiple isoforms. Please see this link to UniProt ( for more details. NB110-41404 should work just fine for you as the only known isoform appears to be cytoplasmic.
