Here we have developed a stable isotope labeling comparative analysis of RNA digests (SIL-CARD) approach, which improves upon the original 18O/16O labeling Title: Stable-Isotope Labeling for Protein Quantitation by Mass Spectrometry VOLUME: 7 ISSUE: 2 Author(s):Kolbrun Kristjansdottir and Stephen J. Kron Affiliation:Ludwig Center for Metastasis Research, 924 E. 57th St., Chicago, IL 60637, USA. heavy stable isotope leads to a mass shift in the mass spectrum, resulting in the observation of peak pairs. The peak heights or areas of su ch pairs can be compared and give an accurate reflection of the difference in abundance of th is peptide between both samples. Heavy stable isotope labels can be introduced at different st ages in the sample trea tment protocol.
