Here we have developed a stable isotope labeling comparative analysis of RNA digests (SIL-CARD) approach, which improves upon the original 18O/16O labeling CARD The chosen isotope can act as a label on that compound that can be identified through nuclear magnetic resonance (NMR) and mass spectrometry (MS). Some of the most common stable isotopes are 2 H, 13 C, and 15 N, which can further be produced into NMR solvents, amino acids, nucleic acids, lipids, common metabolites and cell growth media. IsoCor: Isotope Correction for mass spectrometry labeling experiments¶ Welcome to IsoCor documentation! ¶ IsoCor is a scientific software dedicated to the correction of mass spectrometry (MS) data for naturally occuring isotopes . The use of MS/MS ion intensities and stable isotope labeling, which we term stable isotope labeling tandem mass spectrometry (SILT), decreases the effects of contamination from unrelated compounds. We present a software package (SILTmass) that automates protein identification and quantification by the SILT method.

Abstract: Mass spectrometry has become a routine instrument to identify proteins and peptides from simple or complex samples. Although identification can be confidently determined from a single Isotope ratio mass spectrometry (IRMS) is a technique that has found an increasingly widespread use in archaeology, medicine, geology, biology, food authenticity, and forensic science. IRMS instruments have the ability to accurately and precisely measure variations in the abundance of isotopic ratios of light elements such as 13 C/ 12 C, 18 O 4. Consider the data given in the table below. Determine the average mass of an element based on data table the isotopic abundance and the mass of each isotope – AM=(20x0.9048)+(21x0.0027)+(22x0.0925)=20.19amu Isotope % Abundance 20 Ne 90.48 21 Ne 0.27 22 Ne 9.25 5.
