Cyclic and Disulfide Bridge Peptides
Advanced Peptides specializes in the cyclization and side chain conjugation of peptides.
- Head to Tail cyclic peptides
- Lactam bridge peptides
- Single disulfide bridge peptides
- Multiple disulfide bridge peptides
Head to Tail
Head to tail peptides are easily assembled via the formation of an amid bond between the peptides own N-terminus amine and C-terminus carboxylic acid. We perform the reaction with very high yields, and routinely provide 98%+ purified cycled peptides.
We are able to selectively protect, and then deprotect peptide sidechains to allow for the formation of lactam bridges between Lysine or Diaminopropanoic acid, and Glutamic and Aspartic Acids. We can even perform multiple different sites for bridge formation.
Single and Multiple Disulfide Bridges
We routinely synthesize single and double disulfide bridges on peptides with very high purity yields. We have even designed and performed long chain synthesis, where we have synthesized peptides internally folded with 3 and 4 disulfide bridges.
