Tryptophan Analysis Service

Published: April 15, 2024

Tryptophan is an amino acid, which takes part in protein biogenesis. There are two sources of tryptophan, endogenous protein degradation and daily intake. Tryptophan plays vital role in biological activities, and has interaction with multiple biomolecules, including carbohydrates, proteins, vitamins, etc. MtoZ Biolabs offers tryptophan metabolites analysis service using an ACQUITY UPLC/TripleQuad5500 (Waters/AB Sciex), which has characteristics of high accuracy, specificity, and sensitivity. We guarantee accurate analysis of tryptophan metabolites even in low abundance. With our optimized sample preparation methods, interference from high-abundance dominant metabolites can be hugely reduced, thus further increasing detecting sensitivity.
