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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Compound for derivatizing polypeptides and method for sequencing and quantifying amino acids in polypeptides using the same","description":"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 aci","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8501488","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
