Diagnostic peptide capabilities

Diagnostic (DX) peptides are often used as assay reagents, controls, calibrators, and detection/quantification standards. Below are the most common peptide formats requested for diagnostic workflows under an ISO 13485:2016 quality system.

Custom DX peptides

Defined sequences with controlled manufacturing, targeted purity, and lot-to-lot consistency to support assay validation and kit workflows.

Fluorescent-labeled peptides

Peptides conjugated to fluorophores for detection assays (e.g., binding studies, immunoassays, FRET formats). Common labels include FITC, TAMRA, Cy3/Cy5, and other dyes.

Isotopically labeled peptides

13C / 15N (and other stable isotope) labeled peptides used as internal standards and calibrators for LC–MS/MS quantification and biomarker workflows.

Biotinylated peptides

Biotin-tagged peptides for immobilization and capture formats (streptavidin systems), frequently used in diagnostic assay development.

Peptide conjugates

Peptide-to-carrier or peptide-to-protein conjugates (application-dependent) to support immunoassay reagent formats and analytical workflows.

Documentation & traceability

Audit-ready documentation, traceability, and controlled release deliverables aligned with diagnostic development and regulated production needs.

FAQ

What makes a peptide “diagnostic-grade” for DX workflows?

“Diagnostic-grade” commonly refers to peptides produced with enhanced traceability, controlled documentation, and quality system elements aligned to diagnostic development and regulated production needs (e.g., ISO 13485:2016).

Do you provide fluorescent and isotopically labeled peptides?

Yes. DX projects frequently request fluorescent-labeled peptides for detection formats and stable isotope-labeled peptides for LC–MS/MS quantification workflows. Share your label and assay context and we’ll recommend an optimal approach.

What documentation can be provided under ISO 13485:2016?

Documentation is project-dependent, but may include a CoA, analytical outputs (HPLC/MS), lot identifiers, and traceability elements. If you have specific deliverables or audit requirements, we can align the release package accordingly.

Can you support lot-to-lot consistency programs?

Yes. For diagnostic workflows, lot-to-lot consistency is often critical. We can discuss specifications, testing expectations, and change control considerations to help support continuity across manufacturing lots.

Are DX peptides intended for clinical use?

Intended use depends on your final application and regulatory pathway. This page describes quality system and documentation support; please discuss your intended use and requirements with our team so we can align the appropriate grade and deliverables.
