Amino Acid Analysis Service

Amino acids are fundamental organic compounds with amino and carboxyl groups, serving as the building blocks of proteins and peptides. While approximately 20 amino acids are commonly known for protein synthesis, many more exist in nature. These compounds are essential for various biological processes, including protein synthesis, nitrogen balance, and metabolic regulation. Recent studies highlight their role in regulating glucose and lipid metabolism, maintaining homeostasis, and influencing gene expression, immune responses, and disease development.

MtoZ Biolabs offers amino acids analysis service using GC/MS (Agilent 7890A/5975C) and LC/MS/MS (AB Sciex 5500), which has characteristics of high accuracy, specificity, and sensitivity. We guarantee accurate analysis of amino acid metabolites even in low abundance. With our optimized sample preparation methods, interference from high-abundance dominant metabolites can be greatly reduced, thus further increasing detecting sensitivity.

Analysis Workflow

Sample Submission Requirements

1. Sample Type and Volume

For other sample types and amounts, please contact MtoZ Biolabs.

2. Sample Transportation

Calculate with 3-4 kg of dry ice evaporating per day, please use a sufficient amount of dry ice for transportation (it is recommended to use larger pieces of dry ice, as larger pieces evaporate more slowly), and seal with a foam box. Also, try to choose a faster mailing method to reduce the possibility of sample degradation during transportation.
