Stable Isotope-Labeled Peptide Standards for Quantitative Proteomics
# Stable Isotope-Labeled Peptide Standards for Quantitative Proteomics ## Introduction to Stable Isotope Peptide Standards Stable isotope-labeled peptide standards have become indispensable tools in modern quantitative proteomics. These chemically identical but isotopically distinct peptides serve as internal references, enabling accurate measurement of protein abundance across different samples. The use of these standards has revolutionized our […]
