Can Taros synthesise peptides containing unusual amino acids?

Yes. Taros can work with unnatural or uncommon amino acids and can develop suitable synthetic strategies for peptides that are not straightforward standard sequences.

Which peptide modifications can Taros support?

Possible modifications include fluorescent labels, isotope labels, biotin, tags, phosphorylation, glycosylation, linkers, spacers, polyethylene glycol units and other customer-defined functional groups, subject to feasibility.

Can Taros prepare cyclic, dimeric or peptidomimetic structures?

Yes. Taros can support more complex formats such as cyclic peptides, dimeric peptides, peptidomimetics and customised conjugates.

Does Taros use solid-phase and solution-phase peptide synthesis?

Yes. The synthetic route can use solid-phase synthesis, solution-phase synthesis or a combined strategy depending on sequence, modifications, scale and purification requirements.

What analytical methods are used to confirm peptide quality?

Taros can use methods such as liquid chromatography-mass spectrometry and high-performance liquid chromatography to confirm identity, assess purity and support quality control.

Can Taros advise on peptide purity, solubility and delivery format?

Yes. The team can discuss required purity, amount, modifications, analytical options, overall charge, solubility considerations and the most suitable delivery format for the intended application.

What information is needed for a peptide quotation?

Provide the amino-acid sequence, terminal modifications, labels or tags, desired amount and purity, salt or delivery form, analytical requirements, application and any known stability or solubility concerns.

Custom Peptide Synthesis

Custom peptide synthesis for cutting-edge life science

Due to the rise of biologics in recent years, the industry has expanded the toolbox for drug discovery beyond traditional small molecules. Pharma and biotech companies have increasingly launched protein and peptide drugs on the market. We observe a trend towards peptide therapeutics as they provide a greater chemical diversity than any other class of biological molecules. Apart from its therapeutical application, peptide chemistry is essential for cutting-edge life science, e.g. studying proteins, their synthesis and specific functions. Taros has a great expertise in custom peptide synthesis services of high quality. Peptides ranging from 3-20 amino acid residues on scales up to 1 gram mg while assuring high quality peptide synthesis standards even for complex or unusual sequences, choose Taros Chemicals! As we are not commissioned for the very simple and plain peptide synthesis projects, we do not work with automated peptide synthesizers. Our highly experienced chemists rather work on sophisticated chemistry challenges and customized peptides, e.g. with special modifications and labels. We perform peptide synthesis based on the specific customer needs and requirements, in solid phase as well as in solution phase, in parallel or as a single batch setup. Besides all common peptide modifications, labels and tags we strive for synthesis of more challenging peptides in particular.

Our custom peptide synthesis options typically include:

Unnatural and uncommon amino acids
Isotope labelled and Fluorescent peptides
Biotinylated and tagged peptides
Long, cyclic or dimeric peptides
Different linkers, spacers and PEGs
Peptidomimetics
Peptide pooling and compound library services

Peptide synthesis for research in life science, drug discovery & diagnostics

We offer synthesis services with high success rates and optimize the appropriate peptide synthesis method to suit your requested peptide! We manufacture tailored peptides on demand with our state of the art equipment, while paying close attention to high safety and environmental standards. Our skilled scientists are happy to provide you detailed customer support and aim to overcome all arising problems during your custom synthesis project. We can help you selecting the peptide specifications (e.g. purity and amount of the peptide, modifications, analytical options and the overall delivery formats) to fit your requests. Finding the right specifications for you, Taros provides peptides with high purity ( up to > 98%) and offer advice on how to solubilize the desired product best as well as help on deciding about the desired overall charge of the peptide to fit your application. Applications can range from basic research and fluorescent imaging to high performing dyes with low toxicity with specific modifications available. After each peptide synthesis service, we offer a routinely analysis of the product by LC-MS or HPLC to confirm the exact structure, identity and quality of the custom peptide. Taros also provides the design and production of tailored peptides with modifications, ranging from fluorescent labels, phosphorylation, glycosylation to biotinylation and much more. For detailed information on our custom chemical services please consider our Taros FAQ – here we highlight key issues for potential customers.

Frequently Asked Questions

What custom peptide synthesis services does Taros provide?

Taros develops customised peptides for life-science research, drug discovery and diagnostic applications. The service focuses particularly on complex or unusual sequences, including peptides containing specialised modifications, labels, linkers or uncommon amino acids. Projects may be performed as individual batches or as parallel synthesis programmes according to the customer’s requirements.

Which peptide synthesis methods and modifications are available?

Taros uses both solid-phase and solution-phase peptide synthesis, selecting the method according to the sequence, scale and required modification. Available options include unnatural or uncommon amino acids, isotope-labelled and fluorescent peptides, biotinylated or tagged peptides, cyclic or dimeric peptides, PEG-based linkers and spacers, peptidomimetics, peptide conjugates and peptide libraries.

Can Taros support complex peptides and peptide conjugates?

Yes. Taros focuses on chemistry-intensive peptide projects that may not be suitable for standard automated synthesis. Its scientists can support difficult sequences, specialised functionalisation and peptide–small-molecule conjugates, including retrosynthetic planning, synthesis-route development and the preparation of related analogue variations for medicinal chemistry or biological testing.
