Peptide Modification

Site-specific labeling, conjugation and custom chemistry for research peptides.

Peptide modification expands the utility of a sequence for assays, imaging, pharmacokinetics research and bioconjugation. ChinaPeptides offers more than 400 modification technologies, from routine terminal capping to custom linker chemistry.

Modifications are planned with the synthesis route so that labeling, cyclization or conjugation does not compromise purity or sequence integrity.
