Labelled Peptides

Product List

BOC Sciences is committed to providing customers with the most comprehensive variety of isotope-labeled peptides. We offer a complete range of labeled peptides with stable quality, and our custom peptides labeled with stable isotopes include 2H (deuterium), 15N, 13C.

What are Peptides?

Peptides are organic compounds formed by the dehydration of amino acids and are intermediates of protein hydrolysis. Many peptides are synthesized in the nervous system, lymphoid tissue, and endocrine system. Peptides have strong biological activities and can regulate the functional activities of cells in living organisms, and maintain various roles in medicine, cosmetics, food, and other fields.

  • In the field of medicine: With the continuous development of modern biotechnology, the study of peptide drugs, which can be used for anti-tumor, anti-virus, anti-bacterial, diagnosis, etc., has become increasingly essential for disease prevention and treatment.
  • In the field of cosmetics: Peptides reserved characteristics such as high biological activity, easy absorption, safe and non-toxic, and are widely used in cosmetic products. Bioactive peptides were further advanced with characteristics such as anti-aging, repairing, antioxidant, and other biological functions.
  • In the field of food: Peptides are used as nutritional supplements and functional factors in food products to improve or alter nutritional metabolism, fat metabolism, glucose metabolism, and regulation of nervous systems.

What are Isotope-labeled Peptides?

Isotope-labeled peptides refer to peptides in which one or multiple atoms are substituted by isotopes atoms (such as 2H, 13C, 18O, 15N). Isotope-labeled peptides are mainly used for food safety, metabolomics, proteomics, and other fields.

  • In metabolomics, the position and quantity of isotope-labeled peptides can be tracked in vitro and in vivo to study the metabolic pathways of peptides.
  • In food testing, isotope-labeled peptides are commonly used as internal standards and play important roles in food quality control.
  • In quantitative proteomics, the use of isotopically labeled peptides can achieve accurate quantification of one or more target proteins.
