Description

Dl-Serine (15N) is a stable isotope-labeled analog of the amino acid serine, where the nitrogen atom is enriched with the 15N isotope. This compound is essential for advanced research and analytical applications requiring precise isotopic tracing and quantification. It is primarily utilized by scientists and manufacturers in the fields of nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry, metabolic research, and pharmaceutical development.

Application

• Isotopic Tracer in Metabolic Studies: Used to investigate amino acid metabolism, protein synthesis, and turnover rates in biological systems.
• Internal Standard for Mass Spectrometry (MS): Provides accurate quantification in proteomics, metabolomics, and pharmacokinetic studies due to its distinct mass signature.
• NMR Spectroscopy: Serves as a crucial probe for structural elucidation and dynamic studies of biomolecules, enhancing signal resolution and interpretation.
• Pharmaceutical Research & Development: Employed in the synthesis and testing of labeled drug candidates to study absorption, distribution, metabolism, and excretion (ADME).
• Nutritional Science Research: Used in studies examining protein metabolism, amino acid requirements, and the metabolic fate of dietary components.
• Biochemical Reagent: Acts as a labeled building block for enzymatic assays and the synthesis of more complex isotopically labeled compounds.
