Fluorescent-labeled Peptides

Custom Peptide Synthesis

Fluorescently labeled peptides are peptides covalently conjugated with fluorescent dyes or luminescent moieties. They enable tracking and analysis of peptide distribution and dynamic metabolism in vitro or in vivo, leading to wide applications in receptor-binding studies and drug delivery monitoring.
