GenScript purifies and analyzes its synthetic peptides using reverse-phase and ion exchange HPLC. Ion exchange HPLC is employed when reverse-phase HPLC is inapplicable, such as in the purification of very long peptides or large quantities of peptide.
Peptide Purity and Applications:
Peptide purity is the amount of correct peptide relative to the total analytes that absorb at 214 nm (which may include deleted, truncated, or incompletely deprotected sequences, etc.).
GenScript peptide service offers a selection of purity levels ranging from crude peptide up to more than 98% pure. The following guidelines may help you to find the best purity level for your application.
Immunological applications and polyclonal antibody production
- > 90%: SAR studies, bioassays
- > 95%: NMR, crystallization, in vitro bioassays
- > 98%: NMR, crystallization, sensitive bioassays
All peptide synthesis is subject to GenScript's stringent quality control. The typical delivery consists of lyophilized peptide of the required sequence, purity, and quantity and associated QC reports.
