Custom Peptide Labeling

Fluorescent Labeling, Biotin Labeling, Magnetic Bead Conjugation, Radioactive labeling, Stable Isotope Labeling.

Vantrex Labs offers a wide range of peptide / protein labeling options: fluorescent dyes, stable isotopes, and radioactive labeling. Our qualified chemists can help determine the best option for your research, whether it be for receptor binding, localization, or assay development.

Our chemists can help you determine the best label or modification based on your peptide sequence and experimental conditions. All labeled peptides come with HPLC analysis standard to ensure purity and quality of the product.

A list of our most popular labeling and modifications can be found below. Of course, we can also use more specialized labels upon request.

Available Labeling Options
  • Biotin Labeling
  • Fluorescent Labeling
  • Cy3
  • Cy5
  • FAM
  • FITC
  • Rhodamine
  • Magnetic Bead Conjugation
  • Stable Isotope Labeling
  • ²H (Deuterium)
  • ¹³C (Carbon-13)
  • ¹⁵N (Nitrogen-15)

Custom peptides can also be synthesized with modification by acetylation, phosphorylation, amidation, succinylation, butyrylation, and specific disulfide bridge cross-linking.
