Counterion中文

WebA sodium salt (Na+) is useful for peptides with acidic isoelectric points ( pI) as with those containing several Asp and Glu, as well as a C-terminal acid. In many cases, peptides with free sulfhydryl groups as HCl salts have better stability against potential oxidation impurities. Similarly, salt form choice may impact peptide solubility. http://www.ichacha.net/counterion.html
