 Peptide Purity Grades   
The Peptide Quality Standard
What peptide purity you need for your applications, we made it easy!
Purity of peptides is a critical factor that affects the success and meaningful outcome of a research project. Making a right choice of peptide purity is important while synthesizing a peptide for your applications. This will save time as well as costs during peptide synthesis. CPC Chinese Peptide Company offers three different peptide purity grades to help you decide the right purity that suit your needs.
Peptides are purified using reverse-phase high-performance liquid chromatography (HPLC), though sometimes alternative methods such as ion exchange, dialysis, precipitation or gel filtration chromatography are also used. CPC Chinese Peptide Company ships its peptides with HPLC and mass spectrometry (MS) results to verify the purity level and identity of the peptide. Amino acid analysis, solubility tests, sequencing, peptide content, counter-ion content and moisture also are done as per customer requests. Typically each peptide is delivered as a TFA salt form. For cell research, consider having peptides produced in acetate salt form.
