Abstract
The present invention relates to a compound for N-terminal substitution of polypeptides which is used in sequencing and quantifying amino acids and a method for sequencing and quantifying an amino acid sequence using the same. The method for sequencing and quantifying amino acids in accordance with the present invention leads to a relative quantitative analysis of proteins with very high reliability, and can distinctively discriminate between y-type ions and b-type ions on the MS/MS spectra, providing the means for realization of high-reliability protein identification.
