The required peptide purity percentage depends on your specific application. AmbioPharm can synthesize peptides up to >98% purity. These are some general guidelines for peptide purity requirements:
Purity | Peptide Application or Use |
>80% | Immunological applications and polyclonal antibody production |
>90%* | Structure-Activity Relationships (SAR) studies, bioassays |
>95%* | In vitro bioassays and in vivo biological activity tests, Ph I and early Ph II |
>98% | Pharma-cGMP material with set impurity specifications (late PH II – Ph III and commercial) |
*For peptides utilized for Toxicology studies, it is recommended to have specifications for purity on the lower end, perhaps from 90 – 95%.
