Why are custom peptides supplied as lyophilized powder?
Lyophilization (freeze-drying) removes moisture from peptides under low temperature and vacuum, significantly improving product stability during transportation and long-term storage. Lyophilized peptides are less susceptible to degradation and can be reconstituted with an appropriate solvent before experimental use.
How should lyophilized peptides be stored?
Lyophilized peptides should be stored in a dry, sealed container away from light. For long-term storage, temperatures of -20°C or below are generally recommended. After reconstitution, peptides should be aliquoted when possible and avoid repeated freeze-thaw cycles to maintain stability and biological activity.
How should I reconstitute a lyophilized peptide?
The appropriate solvent depends on the peptide sequence and its physicochemical properties. Common options include sterile water, phosphate-buffered saline (PBS), or suitable buffer solutions. Some hydrophobic peptides may require a small amount of DMSO before dilution. If needed, our technical team can recommend an appropriate reconstitution protocol for your peptide.
What quality control documents are provided with lyophilized peptides?
Each batch of lyophilized peptides undergoes comprehensive quality control before shipment. Standard documentation typically includes HPLC purity analysis, Mass Spectrometry (MS) results, and a Certificate of Analysis (COA). Additional testing or documentation may also be available upon request for specific research or regulatory requirements.
What peptide purity levels are available?
We offer lyophilized peptides with various purity levels to meet different research needs, including crude, >70%, >80%, >90%, >95%, and >99% purity. Higher purity peptides are recommended for applications requiring greater analytical accuracy or biological specificity.
What packaging options are available for lyophilized peptides?
Lyophilized peptides are typically packaged in sterile glass vials with clearly labeled product information. We also provide customized packaging, labeling, batch sizes, and private-label solutions for distributors, laboratories, and OEM partners.
Can you manufacture peptides according to custom sequences?
Yes. We specialize in custom peptide synthesis based on customer-provided amino acid sequences. We also support a wide variety of peptide modifications, labeling, cyclization, and optimization services.
How are lyophilized peptides shipped internationally?
Air transport,most lyophilized peptides are stable enough for international shipment under appropriate packaging conditions. Temperature-controlled shipping options can also be arranged for products requiring additional protection. Each shipment is carefully packed to minimize moisture exposure and ensure product integrity.
Do you provide Certificates of Analysis (COA)?
Yes. Every batch is supplied with a Certificate of Analysis (COA), including peptide identity, molecular weight, purity, analytical methods, and batch information. Additional analytical reports can be provided upon request.
What quantities can I order?
We supply lyophilized peptides in flexible quantities ranging from milligram-scale research samples to gram-scale production. Custom quantities can also be arranged according to your project requirements.
Are your peptides intended for research use only?
Yes. Unless otherwise specified, our lyophilized peptides are supplied exclusively for laboratory research and development purposes. They are not intended for human therapeutic, diagnostic, or veterinary use.
How do you ensure batch-to-batch consistency?
Our manufacturing process follows standardized operating procedures and rigorous quality management systems. Each production batch undergoes comprehensive analytical testing to ensure consistent purity, identity, and performance across batches.
