Programme Highlights

Ultra-Fast Peptide Synthesis

High-quality peptides delivered in 2 weeks. If delayed, it’s on us. T&C info-tooltip
  • Each project will undergo a feasibility assessment before being accepted under the guaranteed peptide delivery program.
  • Upon receipt of your RFQ and/or work plan, our scientific team will conduct a technical review and a formal proposal will be shared, including:
     – Proposed synthesis routes
     – Relevant literature references
     – Key considerations
     – Estimated costs and timelines
     – Delivery terms under the o2h Peptide Guarantee programme
  • Guaranteed timelines apply to:
     – Up to 20 linear peptides with standard modifications and chain lengths of approximately 20 amino acids (via library-type synthesis), or
     – Up to 10 moderately complex peptides involving advanced modifications and requiring microwave-assisted synthesis.
  • Once the proposal is formally approved, the project team will be introduced and we will proceed with procurement of required materials.
  • The turnaround time is calculated from the date of final project confirmation and material availability. The 2-week delivery commitment applies to the production phase, excluding shipping time, and specifically refers to the synthesis turnaround time (TAT) from project initiation.
  • o2h reserves the right to determine project eligibility for the guarantee after internal review.
  • If project-specific information is required, a Confidential Disclosure Agreement (CDA) can be executed to enable open technical discussions.
  • For non-standard peptide projects that do not qualify under this initiative, the o2h team will provide a custom FFS (Fee-for-Service) proposal with a competitive quote and tailored timelines and delivery offers, subject to separate terms and conditions.

    FAQs

    What makes o2h Discovery a preferred CRO partner for peptide synthesis?

    o2h Discovery’s 2-week Peptide Guarantee ensures fast, reliable delivery of high-quality peptides. Combined with rigorous QC, global service, and expert project management, we are a trusted CRO partner for custom peptide synthesis service in drug discovery.

    How does o2h Discovery help accelerate peptide-based drug discovery projects?

    By delivering peptides within a guaranteed 2-week timeframe, we remove synthesis delays. This allows researchers to advance screening, validation, and pipeline development faster than with traditional peptide CRO services.

    How does o2h Discovery deliver peptides faster than other CROs?

    Through optimized workflows, dedicated resources, and an experienced chemistry team, we synthesize and deliver standard linear peptides within 2 weeks without compromising purity or reliability.

    Why should I choose o2h Discovery for my custom peptide projects?

    With o2h Discovery, you get guaranteed timelines, >95% purity, and seamless communication. Our custom peptide synthesis services help minimize risk and accelerate your drug discovery pipeline.

    Can I track the status of my peptide project with o2h Discovery?

    Yes. We provide regular progress updates throughout the synthesis process, so you always know the status of your peptide order.

    How do I submit a peptide project to o2h Discovery?

    Simply share your peptide sequence and project details via our website or email. Once confirmed, your project is placed into our guaranteed 2-week workflow.

    What is the o2h Peptide Guarantee Programme?

    It's a global initiative by o2h Discovery offering custom peptide synthesis delivered in 2 weeks of project initiation. If delayed, it’s on us. This is designed to accelerate early-stage drug discovery by ensuring fast, high-quality, and reliable peptide delivery.

    What types of peptides are covered under the 2-week guarantee?

    Standard linear peptides up to 20 amino acids in length and up to a gram in quantity are covered under our guarantee.

    What purity levels do you provide for peptides?

    All peptides are synthesized at ≥95% purity and come with complete analytical data, including HPLC, MS, and a Certificate of Analysis (COA).

    What is the minimum and maximum scale of peptide synthesis?

    We offer flexible scales, ranging from 1 mg to gram quantities, tailored to your project requirements.

    Is the 2-week Peptide Guarantee available globally?

    Yes, the o2h Peptide Guarantee is available to biotech and pharma companies worldwide. Delivery timelines depend on customs and shipping partners.

    Can you make modified or more sophisticated peptide species, such as cyclic peptides, bi-functional/bi-valent, peptide drug conjugates, modifications such as PEGylation and PTMs, labelled peptides, and so on?

    Yes, we could make the core linear peptide under the guarantee, but the modifications would usually be outside the scope of the peptide guarantee, and we would perform this aspect under our usual service model. Please contact us to discuss how we would approach this for you.

    When does the 2-week peptide turnaround time begin?

    The 2-week turnaround time starts from the date of final project confirmation and material availability. It refers specifically to the synthesis phase and does not include shipping time.

    Are all peptide synthesis projects eligible for the 2-week guarantee?

    No, project eligibility is determined after internal review by the o2h Discovery team. Non-standard peptides or complex sequences may not qualify; in such cases, a custom Fee-for-Service (FFS) proposal will be provided with tailored timelines.
