L-Glutamate Assay Kit II

• ‚hntended use •

<For the food manufacturing industry>

1. Material control 
2. Manufacturing control 
3. Quality control

<For neuroscience and biology laboratories> 
L-glutamate is a critical neurotransmitter. 
L- glutamate has key roles in cell metabolism and disease.


• Characteristics •

1. Accurate quantification
Easy to use kit accurately measures L-glutamate in samples. No special skill is required.

2. Simple handling
  Simple protocol compared to older assays utilizing L-glutamate decarboxylase or L-glutamate dehydrogenase.

3. Low overhead cost
  Room temperature assay reads on standard absorption spectrometer at 600 nm. Does not require expensive specialized instrumentation.
