We Welcome Enquiries From

Peptides up to 192 Amino Acids

This capability allows us to support projects extending significantly beyond conventional short research peptides, including large peptide and protein sequences such as recombinant human growth hormone (somatropin), consisting of 191 amino acids, where technically and legally appropriate.

Depending on the molecule, required quantity and intended research application, different manufacturing and purification strategies may be utilized to achieve the required specification.

Our team can evaluate individual projects based on sequence complexity, purity requirements, quantity, analytical requirements and documentation needs.

Custom Peptide Synthesis

Research does not always begin with an off-the-shelf molecule.

Cellpept therefore welcomes enquiries for custom peptide synthesis, including peptides that are not part of our standard catalogue.

Institutional customers can contact us with their required sequence and specifications. Our team can assess the feasibility of the project and provide information regarding available purity levels, analytical testing, production quantities, lead times and documentation.

Bulk & Institutional Orders

For organizations requiring quantities beyond our standard catalogue formats, Cellpept can provide dedicated quotations for bulk peptide supply.

Depending on the peptide and project requirements, we can accommodate different quantities, concentrations, specifications, packaging configurations and testing requirements.

For ongoing research programs, we can also discuss scheduled or repeat production batches to help institutions maintain consistency between successive orders.

Documentation & Quality Standards

Institutional procurement requires considerably more than simply supplying a peptide. Cellpept places strong emphasis on traceability, analytical verification and professional documentation.

Depending on the product, manufacturing route, jurisdiction and customer requirements, appropriate documentation and analytical packages can be supplied, which may include:

For institutional projects with specific procurement or compliance requirements, please provide these requirements when requesting a quotation so that our team can determine what documentation can be supplied for the particular material.

Independent Analytical Verification

For projects requiring additional assurance, independent third-party analytical testing can be discussed as part of the supply agreement.

Testing requirements can be determined according to the nature of the molecule and the intended research application, including identity and purity verification and, where relevant, additional analytical parameters.

This provides research organizations with independently generated analytical data alongside the manufacturer’s own quality documentation.

From Research Quantities to Larger-Scale Supply

Whether your organization requires a specialized peptide for an individual research project, repeated batches for an ongoing program, or larger-scale supply, Cellpept can evaluate the requirements individually.

Our objective is to provide professional research organizations with a reliable route from sequence to institutional supply:
