Description

Dl-Aspartic-2-13C-15N Acid is a stable isotope-labeled analog of aspartic acid, a fundamental amino acid. This compound is essential for advanced research in metabolic pathway analysis, protein dynamics, and quantitative proteomics, providing critical data for scientific discovery. It is primarily utilized by pharmaceutical R&D teams, academic research institutions, and diagnostic manufacturers developing sophisticated analytical methods.

Application

• Metabolic Flux Analysis (MFA): Used as a 13C and 15N dual-labeled tracer to study central carbon and nitrogen metabolism in cell cultures and biological systems.
• Quantitative Proteomics & Mass Spectrometry: Serves as an internal standard for the accurate quantification of proteins and peptides using techniques like LC-MS/MS, correcting for instrument variability.
• Biomedical Research: Employed in studies investigating neurological function, urea cycle disorders, and amino acid metabolism due to aspartate's role as a neurotransmitter and metabolic intermediate.
• Pharmaceutical Development: Used in the research and development of new drugs, particularly in pharmacokinetic (PK) and absorption, distribution, metabolism, and excretion (ADME) studies with isotope-labeled compounds.
• NMR Spectroscopy: Acts as a valuable probe in Nuclear Magnetic Resonance (NMR) studies for elucidating molecular structure, dynamics, and interactions in complex biological samples.
• Nutritional Science Research: Applied in studies examining amino acid utilization, protein synthesis rates, and nutritional biomarkers in clinical and animal research settings.
