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 and 10 analytes (9 IS and 1 surrogate) for the TCA cycle 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. The LC-MS consists of an Acquity UPLC I-class system interfaced to a Xevo™ TQ-S micro or TQ-XS mass spectrometer. The column is typically a Cortecs™ T3 (2.1x30 mm, 2.7 µm particles). 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.
