L-Tryptophan-15N(Cat No.:S000643) is a stable isotope-labeled variant of the essential amino acid tryptophan, where the nitrogen atom is replaced with the heavier isotope nitrogen-15 (15N). This modification is extensively used in scientific research, particularly in protein structure and function studies through techniques like nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry. By incorporating 15N-labeled tryptophan into proteins, researchers can gain detailed insights into protein dynamics, interactions, and folding processes. This isotope labeling is crucial for elucidating biological mechanisms and understanding protein-related diseases.
