Isotope Labeling Of Protected Amino Acids

Isotope labeling has the advantages of high sensitivity, simple positioning, and accurate quantification, making isotope labeling more and more popular in the fields of medicine and biochemistry. Among them, isotopic labeling of protected amino acids is an important tool for the analysis of protected amino acids in metabolic and proteomic studies. By adding a known ratio of isotopically labeled protected amino acids to the sample, precise measurements of the quantitation and localization of the protected amino acids can be achieved. Alfa Chemistry has powerful isotope labeling technology and can provide different isotope labeling services for different protected amino acids according to customer requirements.
