MASS SPECTROMETRY FOR PEPTIDE, FULLERENE DERIVATIVE, FULLERENE-PEPTIDE COMPLEX, AND THEIR MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a mass spectrometry for peptide to perform mass spectrometry with high sensitivity in a negative mode.;SOLUTION: This mass spectrometry is performed by using a product obtained by reacting peptide with a fullerene derivative comprising a functional group expressed by an expression 1. In the expression, X represents a 3-10C organic group having a structure represented by an expression (a). However, X bonds to a carboxyl group in the expression 1 via a nitrogen atom in the expression (a).;COPYRIGHT: (C)2006,JPO&NCIPI
