Glutamate Dehyrogenase Activity Assay - Information

Assay Genie's non-radioactive, colorimetric GLDH assay is based on the reduction of the tetrazolium salt MTT in a NADH-coupled enzymatic reaction to a reduced form of MTT which exhibits an absorption maximum at 565 nm. The increase in absorbance at 565 nm is directly proportional to the enzyme activity.

Applications

For quantitative determination of glutamate dehydrogenase activity.

Glutamate Dehyrogenase Activity Assay - Key Features

  • Fast and sensitive. Linear detection range (20 uL sample): 0.4 to 80 U/L for 30 min reaction. Detection Limit of 0.1 U/L for 120 min reaction.
  • Convenient and high-throughput. Homogeneous "mix-incubate-measure" type assay. Can be readily automated on HTS liquid handling systems for processing thousands of samples per day.

More Details

GLUTAMATE DEHYDROGENASE (GLDH) is an enzyme which catalyzes the interconversion of glutamate and a-ketoglutarate. Elevated blood serum GLDH levels indicate liver damage; thus, GLDH plays an important role in the diagnosis of liver disease, especially in combination with aminotransferases. Transgenic plants expressing microbial GLDHs are improved in tolerance to herbicide, water deficit, and pathogen infections.

Entrez Gene Summary for GLUD1 Gene

This gene encodesglutamatedehydrogenase, which is a mitochondrial matrix enzyme that catalyzes the oxidative deamination ofglutamateto alpha-ketoglutarate and ammonia. This enzyme has an important role in regulating amino acid-induced insulin secretion. It is allosterically activated by ADP and inhibited by GTP and ATP. Activating mutations in this gene are a common cause of congenital hyperinsulinism. Alternative splicing of this gene results in multiple transcript variants. The relatedglutamatedehydrogenase2 gene on the human X-chromosome originated from this gene via retrotransposition and encodes a soluble form ofglutamatedehydrogenase. Related pseudogenes have been identified on chromosomes 10, 18 and X. [provided by RefSeq, Jan 2016]

UniProtKB/Swiss-Prot for GLUD1 Gene

  • DHE3_HUMAN,P00367
  • Mitochondrialglutamatedehydrogenasethat converts L-glutamateinto alpha-ketoglutarate. Plays a key role in glutamine anaplerosis by producing alpha-ketoglutarate, an important intermediate in the tricarboxylic acid cycle. May be involved in learning and memory reactions by increasing the turnover of the excitatory neurotransmitterglutamate(By similarity).
