Neurotransmitter Analysis Service


Neurotransmitter Analysis Service

Neurotransmitter is an endogenous metabolite that acts as a chemical messenger in carrying, expanding, and regulating signals between neurons and other human cells.

As an important part of the gut-brain axis, gut microbes can affect the brain in many ways. For example, it can secrete and synthesize neurotransmitters (such as aminobutyric acid, dopamine, etc.), produce neurostimulating metabolites that affect the immune system, or produce neurogrowthstimulating substances (e.g., short-chain fatty acids, uranine, etc.), and other pathways (e.g., vagal pathways or the regulation of important dietary amino acids, etc.).

Advantages of Neurotransmitter Analysis Service

  • Advanced platform: Ultra-high resolution, ultra-high sensitivity and fast scanning speed QE HF mass spectrometry platform is used for detection, with large throughput and more compound information can be identified. Multiple reaction monitoring (MRM) technology is used to achieve precise qualitative and absolute quantitative.
  • High-quality database: The primary and secondary mass spectra in the database are all real spectra detected by the high-quality, high-resolution, high-resolution Orbitrap mass spectrometer using standard products. The compound identification accuracy is high.
  • Strict quality control: isotope internal standard calibration, external standard method quantification. Manual proofreading of standards. Standard R2>0.99.
  • Personalized service: Have a professional information analysis team to analyze the data results. Personalized information analysis can also be carried out according to customer needs.
