Metabolomics Standards

CIL offers an array of stable isotope-labeled standards for MS metabolomics research. These are predominantly neat, with the labeling at variable isotopic positions. The metabolite standards are available in different forms (e.g., free acid, salt) and material grades (i.e., research, microbiological and pyrogen tested – MPT). These span a breadth of metabolic classes (e.g., amino and organic acids, fatty acids and lipids, steroids and hormones, vitamins) and biochemical pathways (e.g., glycolysis, pentose phosphate, TCA cycle). They can be used for flux determination and/or relative or absolute quantification of metabolites in biological systems. Research end goals encompass biomarker assessment and therapeutic drug evaluation, among other directions.

Frequently Asked Questions

What is the tolerance for CIL’s 0.1 mg metabolites? The tolerance is ±10% for this unit of metabolites. See the Small Package Sizes flyer for a listing of the key metabolite standards.

Can alternate labeled metabolites be synthesized upon request? Yes, provided they can be synthesized through enzymatic and/or chemical means. Please submit your request to your local sales representative/distributor or complete the on-line Custom Synthesis form. Structure(s), desired quantities, and labeling pattern(s) (if applicable) are required. We will contact you shortly thereafter regarding its feasibility.
