Peptide and Protein Quantification via Stable Isotope Labelling (SIL)

Abstract

To compare protein amounts in different samples from MS/MS data, two different experiment setups exist. Firstly, unmodified proteins can be measured in separate runs at one sample per MS-run. Secondly, proteins of samples to compare can be labelled with small chemical tags, mixed, and measured side-by-side in a single MS-run.

About This Material

This is a Hands-on Tutorial from the GTN which is usable either for individual self-study, or as a teaching material in a classroom.
