Stable Isotope-Labeled Peptide Standards for Quantitative Proteomics
# Stable Isotope-Labeled Peptide Standards for Quantitative Proteomics ## Introduction to Stable Isotope-Labeled Peptides Keyword: Stable isotope peptide standards Stable isotope-labeled peptide standards have become indispensable tools in modern quantitative proteomics. These synthetic peptides, chemically identical to their endogenous counterparts but enriched with stable isotopes such as 13C, 15N, or 2H, serve as internal references…
