Abstract
To provide a method for enhancing analysis sensitivity of bio-related molecules in mass spectrometry. To provide a method for rapidly and conveniently analyzing biological acid molecules using the method of enhanced analysis sensitivity in mass spectrometry. A method of preparing a bio-related molecule to be subjected to mass spectrometry, in which at least a part of acid group(s) is esterified, comprising reacting a bio-related molecule comprising an acid group(s) with a triazene compound to esterify at least a part of said acid group(s). A method of analyzing bio-related molecules comprising reacting a bio-related molecule comprising an acid group(s) with a triazene compound to esterify said acid group(s), and then subjecting said bio-related molecule having an esterified acid group(s) to mass spectrometry.
