Isotope Labeled Amino Acids & Peptides

Isotope-labeled amino acids and peptides are crucial tools in biochemical and biomedical research. Isotope-labeled amino acids contain stable isotopes like carbon-13, nitrogen-15, or deuterium, replacing the corresponding atoms in the amino acid structure. These labeled amino acids are used in protein labeling during synthesis, enabling the tracking of protein turnover, expression levels, and interactions within cells. Isotope-labeled peptides, on the other hand, are short amino acid chains with isotopes, primarily used in mass spectrometry-based proteomics. They serve as internal standards for accurately quantifying protein abundance in complex biological samples. These tools are invaluable for studying protein function, metabolism, and disease mechanisms. They provide insights into cellular processes, and protein-protein interactions, and can aid in identifying biomarkers and potential drug targets, advancing our understanding of biological systems.
