The required peptide purity percentage depends on your specific application. LexinPharma can synthesize peptides
up to >98% purity. These are some general guidelines for peptide purity requirements:
PurityPeptide 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%.
