Labeled Peptides

Custom Peptide Synthesis

Labeled peptides are peptides covalently conjugated with fluorophores, biotin or other modifications. They are commonly used to monitor the in vivo distribution and metabolism of specific peptides, with broad applications in fluorescence imaging, drug–receptor interaction studies, and pharmacokinetics.
