Anaspec peptide synthesis provides custom peptides for research. Learn how Anaspec's services work, quality standards, pricing, and how it compares to other vendors.
Anaspec peptide synthesis is a custom peptide production service from Anaspec, Inc., a life sciences supplier that is now part of Eurofins. The service creates synthetic peptides for laboratory research only, not for human consumption, clinical treatment, or veterinary use. Anaspec provides both catalog peptides and custom synthesis with documentation such as HPLC traces and mass spectrometry data.
What Does Anaspec Peptide Synthesis Offer?
Anaspec offers custom peptides in scales ranging from milligrams to grams. The company supports standard sequences as well as modifications like fluorescent labels, biotinylation, phosphorylation, and stable isotope labeling. Anaspec also sells peptide synthesis reagents, resins, and building blocks, which can simplify procurement for research labs.
Key features of the Anaspec custom peptide service include:
- Sequence design consultation and technical support
- Multiple purity grades, from crude to >98%
- Modifications and conjugations
- Quality control with mass spectrometry and HPLC
- Lyophilized powder packaging for stability
How the Anaspec Custom Synthesis Process Works
Most custom peptides are made using solid-phase peptide synthesis (SPPS). The process follows a standard workflow that gives researchers control over sequence and purity.
- Sequence review: Anaspec checks the requested sequence for difficult residues or aggregation risks.
- Synthesis: Amino acids are added one by one to a resin support.
- Cleavage: The peptide is cleaved from the resin and protective groups are removed.
- Purification: Reverse-phase HPLC separates the target peptide from impurities.
- Quality control: Mass spectrometry confirms molecular weight, and analytical HPLC reports purity.
- Lyophilization: The final peptide is freeze-dried and shipped with a certificate of analysis.
Turnaround time usually depends on peptide length and complexity. Simple peptides may ship in 2 to 3 weeks, while difficult sequences can take longer.
Quality Control and Purity Grades
Anaspec offers several purity levels. Crude peptides are cheapest but contain more impurities. For most cell-based assays, a purity of >95% is recommended. For sensitive applications like structural studies or in vivo research (animal studies), >98% purity is often preferred.
Every custom peptide order includes a certificate of analysis (COA). The COA typically shows the mass spectrometry result, HPLC purity percentage, and the synthesis date. Researchers should always review the COA before using a peptide in experiments.
Anaspec Peptide Synthesis Pricing and Turnaround
Pricing for Anaspec peptide synthesis depends on several factors. The number of amino acids, requested purity, final quantity, and any modifications all affect the final quote. For a rough comparison, peptide synthesis price tends to rise sharply for sequences longer than 20 residues or for purities above 95%.
Typical cost drivers include:
- Length: Each additional amino acid increases reagent and labor costs.
- Purity: >98% purity requires more HPLC time and reduces yield.
- Quantity: Larger milligram or gram amounts cost more.
- Modifications: Fluorescent tags, phosphates, and cyclization add steps.
- Sequence difficulty: Hydrophobic or aggregating sequences may need special handling.
Anaspec does not publish a fixed price list for custom peptides. Researchers should request a quote with the exact sequence and desired specifications. Turnaround is usually 2 to 4 weeks for standard peptides, and rush services may be available for an extra fee.
How Anaspec Compares to Other Peptide Synthesis Providers
Anaspec is one of many vendors offering custom peptide synthesis. The best choice depends on your budget, timeline, and quality requirements. The table below compares Anaspec with several common alternatives.
| Provider | Typical Purity | Turnaround | Notes |
|---|---|---|---|
| Anaspec | >95% standard | 2–4 weeks | Custom and catalog peptides; COA included |
| ProteoGenix | >95% | 2–3 weeks | Specializes in difficult sequences |
| Thermo Fisher | >95% | 3–5 weeks | Large catalog and custom services |
| German custom labs | >98% | 2–4 weeks | EU-based, fast regional shipping |
| Australian custom labs | >95% | 3–5 weeks | Serves Asia-Pacific researchers |
For specialized needs, proteogenix peptide synthesis is known for its proprietary technologies for challenging sequences. Large institutions often consider custom peptide synthesis thermo fisher because of its broad catalog and customer support. In Europe, custom peptide synthesis germany providers offer fast turnaround within the EU.
Researchers should also compare peptide synthesis price across vendors. A low price may come with lower purity or longer lead times. Always check the COA and ask for a sample if possible.
Safety and Regulatory Status of Anaspec Peptides
Anaspec peptides are sold for research use only (RUO). They are not drugs, dietary supplements, or medical treatments. The FDA has not approved any Anaspec peptide for human or veterinary use. Researchers must follow institutional safety guidelines when handling synthetic peptides.
Anaspec peptide synthesis is intended for laboratory research only and must not be used for human consumption or clinical applications.
Some consumers encounter peptides through wellness websites and may search for a make wellness login to buy products. Those consumer products are not the same as research-grade peptides from Anaspec. If you are considering any peptide for health reasons, consult a licensed healthcare professional. Do not use research chemicals as supplements.
Conclusion
Anaspec peptide synthesis provides a reliable custom peptide service for research labs. The company offers multiple purity grades, modifications, and quality control documentation. Pricing depends on sequence length, purity, quantity, and modifications, so request a quote for accurate costs. Always treat Anaspec peptides as research materials and follow all safety regulations.
