Glutamate Assay Kit ab83389 provides a sensitive detection method of the glutamate in a variety of samples.
The glutamate assay kit will only measure free glutamate levels but not glutamic acid found in the backbone of peptides or proteins.
In the glutamate assay protocol, the enzyme mix recognizes glutamate as a specific substrate leading to proportional color development.The amount of glutamate can therefore be easily quantified by colorimetric spectrophotometry at OD = 450 nm.
Glutamate assay protocol summary:
- add samples and standards to wells
- add reaction mix and incubate for 30 min at 37ºC
- analyze with microplate reader
EDTA plasma may not be used with the ab83389 Glutamate Assay Kit. EDTA can interfere with the assay.

RelevanceGlutamate, one of the two acidic proteinogenic amino acids, is also a key molecule in cellular metabolism. In humans, glutamate plays an important role both in amino acid degradation and disposal of excess or waste nitrogen. Glutamate is the most abundant swift excitatory neurotransmitter in the mammalian nervous system. It is believed to be involved in learning and memory and has appeared to be involved in diseases like amyotrophic lateral sclerosis, lathyrism, autism, some forms of mental retardation and Alzheimer's disease. Glutamic acid is also present in a wide variety of foods, and has been used as a flavor enhancer in food industry.
