To expedite method implementation and decrease laboratory downtime/costs, Waters has developed a series of optimized UPLC-MRM/MS methods for a variety of biologically relevant analytes. The MetaboQuan™-R methods enable the rapid (-R), multi-analyte analysis of different classes (e.g., acylcarnitines, amino acids, bile acids, free fatty acids) and pathways (e.g., tryptophan) of metabolites in human biosamples. Although the methods are class-specific, the instrument platform and workflow (i.e., column and mobile phase) is identical across each. This single suite enhances method execution, throughput, and transferability for targeted quantitation in bioanalytical- or biomedical-based metabolomics research.
 
To help facilitate the multi-omics MS analysis of targeted analytes in isotope dilution mass spectrometry (IDMS) applications, CIL is pleased to offer accompanying stable isotope-labeled standards. The internal standards (IS) available for these MetaboQuan-R methods are detailed in the method-specific flyers below (see Resources section). The IS can be supplied individually or as a set. Please inquire for details.

Frequently Asked Questions 

How many analytes are targeted in the MetaboQuan-R methods?

The panels consist of 20 acylcarnitines (12 IS and 8 surrogates), 29 amino acids (27 IS and 2 surrogates), 16 bile acids (15 IS and 1 surrogate), and 26 free fatty acids (15 IS and 11 surrogates). Also included in the method panels are 8 analytes (as IS) for tryptophan pathway analysis. Note, these analytes are analyzed in a multiplexed manner using a common platform/workflow, but with one metabolic class targeted per method (e.g., acylcarnitines run independently from amino acids).

On what LC-MS platform is sample processing achieved?

The metabolites are processed via UPLC-MS/MS.  This workflow involves a Cortecs™ T3 (2.1x30 mm, 2.7 µm particles) column (contained within an Acquity UPLC I-class system) interfaced to a Xevo™ TQ-S micro or TQ-XS mass spectrometer.  The instrument settings (e.g,. retention tims, ionization mode, MRM transitions) are all preprogrammed in the Quanpedia method file supplied in the Waters methods package (see Resources section for contents).

What are the method run times?

The LC gradients are method-dependent and are generally completed in <2.5 min.

What informatic tools are used in data analysis?

TargetLynx is used for data review and compound quantification.

Does CIL offer custom synthesis or custom mix services?

We will evaluate all requests provided that certain compound details are provided (see custom synthesis request or custom mix request form).  Please complete and submit the form(s) on-line or contact your local sales representative.
