2.What is peptide purity? Jul 9,2019

Peptide purity is the amount of the target peptide as determined by HPLC at 214 nm, where the peptide bond absorbs. Water and residual salts are not detected by UV spectrophotometer. Other impurities that can be found in the content include deletion sequences (shorter peptides lacking one or more amino acids of the target sequence), truncated sequences (generated by capping steps to avoid the formation of deletion peptides), and incompletely deprotected sequences (generated during the synthesis or the final cleavage process).
