Modified/Fluorescent Labeled Peptides
Peptide modification mainly modifies the backbone and side chain groups of the peptide. The modified peptide can significantly reduce immunogenicity, reduce side effects, improve solubility, prolong the duration of action in the body, and change the distribution in the body.
GenCefe provides over 300 different peptide modification groups, including: N-terminal modifications, C-terminal modifications, fluorescent labeling, cyclic peptides, biotin labeling, etc.
