Antibody-Based Proteomic Analysis of Apoptosis Signaling

Part of the Methods in Pharmacology and Toxicology book series (MIPT)


Reagents that assess activation of apoptosis and associated signaling pathways are critical for greater understanding of the molecular basis of programmed cell death. The advent of proteomic technologies to probe these events allows monitoring of hundreds to thousands of proteins, as well as sites of posttranslational modification involved in apoptosis at one time. This view of apoptosis at a network level is a powerful tool in studying known apoptotic pathways, as well as elucidating novel signaling events that affect or are affected by apoptotic signaling. The following is a detailed method for successful proteomic profiling of apoptosis using antibody-based enrichment methods along with a liquid chromatography–tandem mass spectrometry analytical platform.
