Quality control documentation provided with every peptide includes mass spectral and HPLC analyses determining composition and purity. Amino acid analysis is available upon request. We also provide storage and handling guidelines.
“Research-grade” peptides are intended for laboratory and research purposes only!
They may not be used as drugs. GMP-API’s are sterile products monitored for chemical and biological contaminants applicable to humans. All AAPPTec catalog peptides are research grade unless specifically noted otherwise.
We have both manual and automated synthesizers.
PepMixes are peptide pools generated by chemical synthesis and pooling of individual 15meric peptides overlapping by 11 amino acids, spanning entire protein antigens or of selected MHC class-I or class-II-restricted epitopes.
The best solvent to dissolve a PepMix is DMSO, followed by slow dilution with an appropriate buffer system. Please note that dissolved peptides have a limited stability. Therefore, we recommend immediate freezing of aliquots that you will not use shortly after dissolution. JPT also offers freeze dried pool aliquots.
The number of peptides that can be screened on a single SPOT peptide array membrane depends on the membrane size, peptide length, and array design. Standard membranes typically accommodate hundreds to thousands of individual peptide spots, enabling high-throughput screening in a single experiment.
We provide analytical documentation for our peptides, which may include a Certificate of Analysis (COA) with batch-specific information such as peptide identity, purity, molecular weight, and quality control testing results. Available documentation may vary by product and batch.
Research peptides are short chains of amino acids used in laboratory and scientific research. They are commonly studied to better understand biological processes and are supplied for research purposes only.
Storage recommendations vary by product. Most lyophilized peptides should be stored in a cool, dry environment, while long-term storage may require refrigeration or freezing. Always follow the storage instructions provided with the product.
Yes, we offer international shipping to many destinations where permitted by applicable laws and regulations. Shipping availability may vary by country.
