Peptides hold immense promise as therapeutic molecules, but many native peptides face challenges such as rapid degradation, poor bioavailability, or limited target specificity. Fortunately, peptide modifications offer powerful strategies to overcome these limitations and enhance the utility of peptides in both research and clinical applications. 

At GenCefe Biotech, we provide a comprehensive suite of peptide modification services designed to tailor peptide performance for specific applications. 

Key Types of Peptide Modifications: 

1.Cyclization 

By forming a covalent bond between the N- and C-terminus or side chains, cyclic peptides can resist proteolytic degradation and gain structural rigidity, often leading to improved receptor binding and stability. 

2.PEGylation 

Attaching polyethylene glycol (PEG) chains can increase the molecular size of peptides, prolong circulation time in vivo, and reduce immunogenicity, making them suitable for systemic administration. 

3.Lipidation 

Conjugating lipids such as palmitic acid to a peptide can promote cell membrane interaction and improve pharmacokinetics. Lipidated peptides often show enhanced oral bioavailability and tissue penetration. 

4.Phosphorylation and Methylation 

These post-translational modifications can modulate peptide activity and are essential in studying protein signaling pathways. 

5.Fluorescent Labeling 

Useful in imaging and tracking, fluorescent dyes can be attached at specific positions to enable monitoring of peptide behavior in vitro and in vivo. 

Benefits of Peptide Modification: 

     ●      Extended half-life in biological systems 

     ●      Increased bioavailability 

     ●      Enhanced target binding or selectivity 

     ●      Improved solubility and stability 

     ●      Facilitated cell or tissue targeting
