AffiASSAY® Glutamate Colorimetric Assay Kit

The AffiASSAY® Glutamate Colorimetric Assay Kit provides a reliable method for the quantification of glutamate in various biological samples. This assay kit offers a colorimetric detection method, enabling researchers to study glutamate metabolism, neurotransmission, and neurodegenerative disorders with precision and convenience.

Key Features:

  • High Sensitivity: The assay kit can detect low levels of glutamate, ensuring accurate quantification in biological samples.
  • Wide Application: The AffiASSAY® Glutamate Colorimetric Assay Kit is compatible with various sample types, including brain tissue homogenates, cerebrospinal fluid, and cell lysates.
  • Quick and Easy: With a streamlined protocol, you can obtain results rapidly, saving time and resources in the laboratory.
  • Cost-Effective: Our kit provides an affordable solution for measuring glutamate levels, reducing experimental costs without compromising data quality.

Assay Principle:

The assay kit measures glutamate based on the enzymatic oxidation of glutamate by glutamate dehydrogenase (GLDH) to generate a colorimetric signal. The signal intensity is directly proportional to the glutamate concentration in the sample.


  • Neuroscience Research: Investigate glutamate signaling, excitotoxicity, and synaptic transmission in neurological diseases such as Alzheimer's disease and Parkinson's disease.
  • Metabolism Studies: Study the role of glutamate in amino acid metabolism, energy production, and neurotransmitter synthesis.
  • Drug Discovery: Screen for compounds that modulate glutamate levels or activity as potential therapeutics for neurological disorders.

Kit Contents:

  • Glutamate Assay Buffer
  • Glutamate Enzyme Mix
  • Glutamate Probe
  • Microplate (96 wells)
  • Glutamate Standard
  • Detailed Protocol

AffiASSAY® Glutamate Colorimetric Assay Kit Protocol:

[Please note that this protocol is a general guideline, and you should always refer to the specific instructions provided in the kit manual for accurate and detailed information.]

Materials Needed:

  • AffiASSAY® Glutamate Colorimetric Assay Kit
  • Biological samples containing glutamate
  • Microplate reader capable of measuring absorbance at 450 nm
  • Pipettes and tips
  • Microcentrifuge tubes


Standard Curve Preparation:

  • Prepare a series of standard solutions containing known concentrations of the glutamate standard provided in the kit.
  • Dilute the Glutamate Probe with Glutamate Assay Buffer to prepare the working solution.
  • Add the working solution to each standard solution to initiate the reaction.

Assay Plate Setup:

  • Label the microplate wells according to your experimental design, including wells for your samples, standards, and controls.
  • If using controls, prepare control samples without glutamate to serve as background controls.

Sample and Standard Addition:

  • Add 50-100 µL of your prepared samples and standard solutions to the appropriate wells on the microplate.
  • Ensure that the final reaction volume in each well is consistent.

Assay Reaction:

  • Prepare the Glutamate Assay Buffer by diluting as instructed in the kit manual.
  • Add the Glutamate Enzyme Mix and Glutamate Probe to each well to initiate the reaction.
  • Incubate the microplate at the appropriate temperature (as specified in the kit instructions) for a recommended time to allow the enzymatic reaction to proceed.

Colorimetric Measurement:

  • After the incubation period, measure the absorbance at 450 nm using a microplate reader.

Data Analysis:

  • Calculate the glutamate concentrations in your samples based on the absorbance readings and standard curve generated from the standard solutions.

Results Interpretation:

  • Interpret and analyze your results according to your research objectives.
  • Observe any variations or trends in glutamate levels among your samples.

Data Presentation:

  • Prepare your data for presentation or publication, and include the appropriate statistical analysis if required.


  • Dispose of all waste materials, including used assay components, according to your laboratory's safety protocols.
  • Always refer to the specific instructions provided with the AffiASSAY® Glutamate Colorimetric Assay Kit for any kit-specific details or variations in the protocol.
  • Additionally, ensure that you adhere to the best practices and safety guidelines in your laboratory while conducting the assay.
