Validation Data Gallery

• 

  FC experiment of Jurkat using CL555-11037

  1X10^6 Jurkat cells were intracellularly stained with 0.4 ug CoraLite® Plus 555 Anti-Human Glutamine Synthetase (CL555-11037) (red), or 0.4 ug Rabbit IgG Isotype Control (CL555-30000)(blue). Cells were fixed with 4% PFA and permeabilized with Flow Cytometry Perm Buffer (PF00011-C).

Tested Applications

• Positive FC (Intra) detected in: Jurkat cells

Recommended dilution

• Flow Cytometry (FC) (INTRA): FC (INTRA) : 0.40 ug per 10^6 cells in a 100 µl suspension

It is recommended that this reagent should be titrated in each testing system to obtain optimal results.

Background Information

GLUL(Glutamine synthetase) also named GS and GLNS, belongs to the glutamine synthetase family. This enzyme has 2 functions: it catalyzes the production of glutamine and 4-aminobutanoate (gamma-aminobutyric acid, GABA), the latter in a pyridoxal phosphate-independent manner By similarity. Essential for proliferation of fetal skin fibroblasts(PMID:18662667). Defects in GLUL are the cause of congenital systemic glutamine deficiency (CSGD). Organismal glutamine production is augmented secondary to an increase in the activity of glutamine synthetase in the lung and skeletal muscle(PMID:7630137). There are other bands with higher (66 kDa, 97 kDa) and lower (30 kDa)molecular weights also detected besides the 42 kDa band indicating the proteolysis of GLUL protein by the ubiquitin system(PMID:10091759).
