Fluorescent labeling
Besides FAM and TAMRA we offer a wide range of dyes.
Biotinylation
Choose between biotin and desthiobiotin to enable your peptide to bind to streptavidin, avidin or other biotin-binding proteins.
Non-proteinogenic amino acids and D-amino acids
Vary the properties of your peptide by choosing the appropriate non-proteinogenic or unnatural amino acid.
Azide-alkyne cycloaddition
Upon request, we can introduce suitable azides or alkynes into your peptide sequence.
Stable isotopes
We can synthesize your peptide sequence with 15N, 13C or deuterium labeled amino acids at the desired location.
Cyclic modification
We can cyclize your peptide at main or side chains, for example via disulfide, thioether or amide bridges or using ring-closing metathesis.
Branched peptides
Depending on your needs, your peptides can be synthesized with two or more branches.
Methylation
Choose from a variety of methylations: nitrogen, α- or β-carbon, Arg, Glu or Asp side chains and more.
Phosphorylation
In addition to phosphorylation of tyrosine, threonine and serine, we also offer phosphomimetics and sulfotyrosine peptides.
Lipidation
Myristic, palmitic and stearic acids as well as other lipids can be coupled N-terminally or via side chains during the synthesis of your peptide sequence.
Glycosylation
We offer N- and O-glycosylation of different amino acids within your peptide.
Acetylation
Upon request, we can perform terminal acetylation of your peptide or acetylation of specific side chains.
Conjugates
We’ll be happy to conjugate your peptide to various proteins such as KLH, OVA, BSA, the diphtheria toxoid and many more.
Chelators
To produce metal ion complexes, we can couple your peptide to various chelators, for instance DTPA, DOTA, NOTA and NODAGA.
PEGylation
Our portfolio includes modification with short- to long-chain and branched polyethylene glycols.
