Introduction

Over the past three decades in the biotech industry, we’ve seen how much is at stake when you choose a peptide partner for your research. “Latest questions that you may have about peptide synthesis before order” is not just a phrase;  it is exactly what we hear from oncologists, immunologists, and biotech teams when they are about to start their next project.

At Intavis Peptide Services, we offer custom peptides for research in various fields, including oncology, immunology, and infectious diseases. We work on project-based collaborations with academic labs, biotech companies, and pharmaceutical partners, not as a lifestyle or consumer supplier. Based on hundreds of conversations with our customers, we have compiled and addressed some of the most frequently asked questions that arise before placing an order.

Who is Intavis Peptide Services actually?

Does Intavis Peptide Services accept orders from private individuals, or only from oncologists, doctors, and scientists?

Intavis Peptide Services has a clear mission. That is to have a significant role in the health industry and peptide therapeutics, and by considering this, our typical partners are:

• Any academic research groups that want to take advantage of the unique and versatile properties of peptides to explore fundamental biological processes.
• Any Biotech and pharmaceutical companies that are developing peptide-based therapeutics, diagnostics, and research tools. The focus areas in this field include oncology, immunology, and infectious diseases, while extending to other areas of medicine and life sciences.
• Any Clinicians and medical professionals who investigate, administer, and evaluate peptides in patient care and clinical studies to help translate peptide science into real-world medical applications.

We do not process orders from private individuals or for personal use. The projects we are supporting originate from an institutional or corporate context, where peptides are integral to a clearly defined research, development, or clinical workflow. This focus allows us to consistently meet the quality standards and expert support our customers require.

What exactly does custom peptide synthesis mean? compared to off-the-shelf or catalogue peptides?

Custom peptide synthesis involves producing peptides tailored to your project, based on your specific sequence and requirements, rather than offering a fixed list of products.

In practice, this means:

• You define the sequence, length, and any modifications (e.g., non-natural amino acids, labels, linkers, stapling).
• We adapt synthesis strategy, purification, and QC to match your intended application – from in vitro assays to complex cell-based or in vivo studies.
• You receive documentation and analytical data (e.g., HPLC, MS, additional QC on request) linked to your exact peptide batch.

In contrast, catalogue peptides are typically standardized products with fixed sequences, formats, and limited customization options. With custom synthesis, the peptide is not “generic”; it is a purpose-built tool, designed to fit your target, assay, and scientific question.

Which kinds of peptide applications are within your scientific focus, and which types of requests are outside the scope of our services?

Our scientific focus is on research and medically relevant applications where peptides play a central role as tools or candidates in…

• Disease-focused applications: Oncology, immunology, and infectious diseases.
  (e.g., neoantigens, vaccine-related epitopes, epitope studies, antimicrobial peptides)
• Mechanistic and chemical biology applications: Target validation, pathway modulation, and molecular imaging.
  (e.g., peptides to modulate or visualize signalling pathways, peptide-based probes, or peptide inhibitors of protein–protein interactions)
• Translational applications: Drug discovery, lead optimization, and development of peptide-based therapeutics
  (e.g., peptidomimetics, peptide libraries, and arrays for screening and optimization)

Outside our scope are peptide requests that are primarily lifestyle-, performance-, or end consumer-driven, such as those for personal enhancement, fitness, anti-aging, or cosmetic purposes. By focusing on research and clinically oriented projects, we ensure that our expertise, quality systems, and communication are fully aligned with the needs of scientists, clinicians, and R&D teams, rather than the consumer market.

What types of peptides and formats can you synthesize (e.g., linear peptides, modified peptides, labelled peptides, peptide libraries, peptide arrays)?

• Customized Peptides

- Synthesis of linear peptide from milli- to multi-gram scale.
- Extensive range of available peptide modifications, ranging from non-natural and D-amino acids over fluorophores and affinity tags to lipids and stable isotopes.
- Constrained peptides through stapling and cyclization techniques to further enhance properties like binding affinity or proteolytic stability.

• Customized Formats

- Peptide libraries in 96-well format with full quality control and documentation.
- Peptide Arrays with up to 600 peptides on a reusable membrane or glass plate for high-throughput screenings. Read more on our Custom SPOT-membrane and CelluSpots™ Peptide arrays brochures.

What information do we need from our customers to start a custom peptide project (sequence, length, purity, scale, application, special modifications)?

To evaluate and quote your project efficiently, we usually need:

• The amino acid sequence(s) of the peptide(s) as one- or three-letter code. We also offer design services like epitope screenings.
• The purity and amount of peptide required for your purposes. Based on our experience, we will help you find the parameters to meet your requirements.
• The planned modifications in the peptide sequences.
• The library size, which offers a great opportunity to reduce the overall costs of your peptides.
• The intended application can help us to help you find the ideal peptide solution, such as for assays in vitro, in cellulo, or for models in vivo.

While a clear description of your biological question and experimental setup supports the straight-up order of peptides, we are happy to provide expertise from our diverse team of scientists to support your project as efficiently as possible.

Which quality levels and analytical data (e.g., HPLC, MS, additional QC) do you provide, and how do these influence the reliability of my experiments?

For most research projects, HPLC and MS data are the standard analytic requirements. However, for more demanding applications, such as peptide terapeutics for in vivo studies or neoantigen cancer vaccinations, the highest QC standards and their documentation are required to ensure safety and consistent biological performance.
Typical analytical options include:

• HPLC: Provides the peptide purity based on UV-vis measurements.
• Mass spectrometry (MS): Confirms the correct molecular mass of the peptide.
• There are more services we offer

- Full Certificate of Analysis (CoA)
- TSE and BSE-free

How do lead times, synthesis scales, and pricing typically look for research-grade oncology or immunology peptides compared to simple catalogue peptides?

• Sequence length and complexity (e.g., 10-mer vs 40-mer, number of modifications).
• Purity and scale (e.g., a small amount at standard purity vs larger quantities at very high purity).
• Analytical and characterization requirements (basic vs extended QC; binding studies, library work, etc.).

Projects involving complex modifications (e.g., photoswitches, staples, multiple non-natural amino acids) or large libraries naturally require more synthesis and optimization steps than standard linear peptides. We always aim to give realistic lead times so that you can plan your experiments without unnecessary delays.

Conclusion

Custom peptide projects succeed when scientific expertise, manufacturing excellence, and quality systems work seamlessly together. At Intavis Peptide Services, we focus on research and medical peptide applications.
