Description
This application note shows that AAA-Direct can be used to determine peptides with lysine hydroxylation. All common amino acids, including hydroxylysine (Hyl), were separated by AAA-Direct, and the presence or absence of Hyl in the fractions confirmed peak identities. The techniques described in this application note show several ways that peptides can be evaluated for identity and purity, how peptides can be desalted, and how much desalting is needed for successful AAADirect amino acid analysis.| Market: | BioPharma |
