L-Glutamate Assay Kit Price
Product Description: The non-essential amino acid glutamate is a key molecule in cellular metabolism, serving as an intermediate in
transamination and deamination reactions, which allows nitrogen from amino acids to be excreted. Glutamate is also a critical neurotransmitter
involved in learning and memory. In brain injury however, glutamate accumulates outside cells, causing excitotoxicity. In the food industry, glutamate
is widely used as a flavor enhancer. The side chain carboxylic group has a pKa of 4.1, thus conferring a negative charge at physiological pH. Our
non-radioactive colorimetric glutamate assay is based on the reduction of the tetrazolium salt INT in a NADH-coupled enzymatic reaction to
formazan, which is water-soluble and exhibits an absorption maximum at 492 nm. The intensity of the red color formed is increased in the presence
of increased L-glutamate. Please note that tissue, plasma, and serum samples need to be deproteinized prior to assay. Each kit is sufficient for 200
microassays. The Assay Solution should be stored at -80ºC, and will remain stable indefinitely at -80ºC. The product is for research use only.

Biomedical Research Service
& Clinical Application
Heart tissue extracts were prepared
from normal hamster (F1B strain) and
cardiomyopathic hamster (TO2 strain),
and deproteinized by 10% TCA for
L-Glutamate assay. The study shows
that the cardiomyopathic heart contains
an increased level of L-glutamate due to
chronic myocyte degeneration.
