Stable Isotope Labeling by Amino Acids in Cell Culture (SILAC) is a powerful technique in proteomics that allows the quantitative analysis of protein expression in different cell populations. SILAC leverages the incorporation of non-radioactive, stable isotopes of amino acids into cellular proteins, enabling comparative studies of protein abundance across different experimental conditions. This technique is particularly valuable in studying changes in protein expression levels during cellular processes, such as differentiation, disease progression, or response to drugs.

Technique Overview

1. Cell Culture and Labeling:
- Cells are cultured in media containing amino acids labeled with stable isotopes. Commonly used isotopes include ^13C or ^15N, which are non-radioactive and do not alter the chemical properties of the amino ___ ___ ______ ________ _______ __________ ___.
