Prices and discounts may vary depending on the peptide length, complexity and order volume. There is a minimum charge of $80/peptide. With our low price guarantee, we promise to match any reputable competitor's price.
How do you ship, and how long does it take to ship to me?
All peptides will be shipped in lyophilized powder, at room temperature. Delivery is overnight within the USA and Canada, and typically takes 3-4 days to reach researchers in other countries.
What analytical data do you provide for peptides?
Each peptide comes with a CoA, MS spectra, and HPLC chromatograms. Please take a look at our peptide sample QA report. We can provide additional analysis if required, e.g. peptide content analysis, TFA content analysis, and KF test (water content test).
What are the applications for your synthetic peptides?
Synthetic peptides are used across a broad range of research and development areas. Applications include:
- Disease biomarker discovery
- Drug target screening
- Cancer research
- Vaccine design
- Epitope mapping
- Antibody production
- The study of protein functions and receptor interactions
What is the maximum length of a peptide you can synthesize?
Biomatik can synthesize peptides up to 130 aa. Unlike many peptide suppliers who are only comfortable in making peptides under 30 or 40 aa, Biomatik has extensive experience in making peptides ranging from 40 to 90 aa. However, the success rate decreases when it comes to longer peptides, especially 100 aa or longer. If you plan to synthesize a sequence of 130 aa or longer, please contact us for our custom protein expression and purification service.
What if you can’t synthesize or purify my peptide?
Each peptide has its own specific characteristics. If any problems occur during the synthesis, and we cannot deliver your peptide on time, we will inform you as soon as possible. If we are not able to make the peptide, you will not be charged as per our ‘no peptide, no charge’ policy.
How do I choose the right peptide purity level?
The required peptide purity level depends on your specific application. For general screening assays or antibody production, lower purities such as crude or >70 % may be sufficient. For functional studies, quantitative assays, or therapeutic development, higher purities (typically 90–98 %) are recommended. For detailed guidance, please refer to our peptide purity guidelines.
What should I consider when designing a custom peptide?
Effective peptide design depends on factors like length, solubility, and sequence composition. Biomatik recommends avoiding sequences that are highly hydrophobic, rich in repeating residues, or prone to aggregation. Adding charged residues or spacers can improve solubility. For epitope peptides, selecting exposed regions of the target protein is ideal. For more tips, see our peptide design guideline, or contact us for advice.
How should I handle and store my synthetic peptide upon delivery?
Synthetic peptides should be stored at -20 °C or below in a dry, sealed container. Before use, allow the vial to reach room temperature to prevent moisture condensation. Peptides may be dissolved in sterile water, buffer, or organic solvent depending on their sequence. Aliquoting and avoiding repeated freeze-thaw cycles is strongly recommended. For full instructions, see our peptide handling guidelines.
What types of peptide modifications do you offer?
Biomatik offers over 300 types of peptide modifications, including common options like acetylation, amidation, phosphorylation, fluorescent labeling (e.g. FITC, FAM, biotin), cyclization, and conjugation to KLH or BSA. More specialized modifications like isotope labeling, PEGylation, and glycopeptides are also available. For a full list, download our peptide modifications PDF.
What are the Peptide Synthesis Techniques Used at Biomatik?
At Biomatik, we use solid-phase peptide synthesis (SPPS) – a widely used and efficient method that builds the peptide from the C- to the N-terminus – to generate high-quality peptides for research. This process involves the stepwise addition of N-protected amino acids, anchoring to a resin, and repeated coupling, washing, and deprotection cycles until the sequence is complete. The final peptide is then cleaved from the resin and purified.Biomatik offers over 300 peptide modifications at affordable prices to support specific experimental needs. Common options include acetylation, amidation, fluorescent labeling (e.g. biotin, FITC, FAM), phosphorylation, cyclization, PEGylation, and KLH or BSA conjugation. Advanced options include isotope labeling, stapled peptides, and a variety of glycopeptide modifications.
