Aliquotation

Peptides are most stable if stored freeze-dried at -20°C or -80°C. If you plan on using small amounts of your peptide over a period of time, please inquire for our inexpensive aliquotation service! Small freeze-dried (lyophilized) aliquots will be stable for much longer than frozen stock solution aliquots or bulk aliquots that undergo repeated freeze-thaw cycles.

Peptide Pooling

We prepare customized peptide pools according to your specific needs and ensure presence of all peptides within a pool even for large peptide numbers using a validated pooling protocol.

You could order one peptide pool containing all your peptides or several smaller subpools or even complex matrix pools for easy epitope mapping. Our customer support is happy to aid you with pool design.

Freeze-dried vs Dissolved Peptides

Peptide stability is highly sequence-dependent, but if stored freeze-dried (lyophilized) at -20 or -80°C, most peptides will be stable for 6 months or even longer.

However, we are also able to provide dissolved peptides (e.g. in DMSO). Please be aware that dissolved peptides need to be shipped frozen and should not be stored long-term due to enhanced decomposition speed in solution! If peptides are to be used frequently over a period of time, make sure to order smaller aliquots, store them frozen at -20°C or – 80°C and avoid freeze-thaw cycles.

Immobilized Peptides

Immobilized peptides can be used for a number of solid-phase assays. We are able to provide your peptides displayed on glass slides as PepStar™ Microarrays, on cellulose membranes as PepSpots Arrays or in multiwell plates as Peptide ELISA.

Delivery Temperature

Most freeze-dried peptides are stable at room temperature for several days. However, please store your peptides in a freezer at -20°C or -80°C upon arrival. However, if purity and quality of your peptides is especially crucial (e.g. for clinical applications), we are able to deliver your peptides on dry ice and including temperature tracking. Please do not hesitate to contact our customer support if you have any further questions.

Key takeaways

Lyophilized powders remain the research standard for peptide studies, offering the longest shelf life (3–5 years at -20°C) and near-complete bioavailability when reconstituted, but require preparation before use.
Ultra-short bioregulator peptides (2–4 amino acids, <500 Da) exhibit fundamentally different oral absorption characteristics than larger peptides, with di- and tripeptides transported intact through the intestinal PepT1 transporter rather than requiring hydrolysis first.
Sublingual liquid preparations bypass gastrointestinal degradation entirely by absorbing through the richly vascularized oral mucosa, offering faster onset than capsules with no proteolytic exposure.
Topical formulations operate near the passive transdermal permeation limit of ~500 Da, with bioregulator peptides at this molecular weight boundary requiring permeation enhancement strategies for reliable skin penetration.
The choice of peptide delivery formats introduces variables that affect experimental design – researchers should match format selection to their specific study objectives rather than assuming equivalence across routes.

01Frequently Asked Questions: Peptide Delivery Systems

What are the main barriers to oral peptide drug delivery? The primary challenges are degradation by digestive enzymes, poor permeability across the intestinal lining, and rapid transit through the GI tract. Innovative coatings, permeation enhancers, and carrier systems are being developed to address these issues. How do peptide-drug conjugates (PDCs) improve CANC therapy? PDCs use targeting peptides to deliver cytotoxic drugs directly to CANC cells, increasing efficacy and reducing side effects compared to conventional chemotherapy. Are peptide-based mRNA delivery systems clinically available? While still largely in the research phase, peptide-based mRNA delivery systems show great promise for gene therapy, vaccines, and protein replacement, with several candidates advancing toward clinical trials. What diseases are most impacted by advances in peptide delivery? Metabolic disorders (diabetes, obesity), CANC, cardiovascular diseases, rare genetic conditions, and infectious diseases are among the primary beneficiaries of innovative peptide delivery systems.
