Stable Isotope-Labeled Lysine

CIL offers a broad assembly of isotope-enriched, L-lysine (L-Lys) compounds for use in MS- or NMR-based, metabolomics and proteomics research.  This list encompasses uniform and partially labeled L-Lys, with the isotopes (¹³C, D, and/or ¹⁵N) at non-exchangeable positions. The material grade is research or microbiological/pyrogen tested (MPT).

Please view the availability, pricing, and specifications of our labeled L-Lys offerings below and inquire if alternate labeling is required. For additional information, refer to our Stable Isotope Standards for Mass Spectrometry and Stable Isotopes for Biomolecular NMR catalogs.
