Identifying transient protein-protein interactions in EphB2 signaling by blue native PAGE and mass spectrometry

Protein complexes in the archaeon Methanothermobacter thermautotrophicus analyzed by blue native/SDS-PAGE and mass spectrometry.

Methanothermobacter thermautotrophicus is a thermophilic archaeon that produces methane as the end product of its primary metabolism. The biochemistry of methane formation has been extensively studied and is catalyzed by individual enzymes and proteins that are organized in protein complexes. Although much is known of the protein complexes involved in methanogenesis, only limited information is...

Analysis of membrane protein complexes by blue native PAGE.

Blue native polyacryamide gel electrophoresis is a special case of native electrophoresis for high resolution separation of enzymatically active protein complexes from tissue homogenates and cell fractions. The method is powerful between 10 and 10,000 kDa. Also membrane protein complexes are separated well after solubilization of complexes with mild neutral detergents. The separation principle ...

Probing protein-protein interactions with mass spectrometry.

Resolving Affinity Purified Protein Complexes by Blue Native PAGE and Protein Correlation Profiling

Most proteins act in association with others; hence, it is crucial to characterize these functional units in order to fully understand biological processes. Affinity purification coupled to mass spectrometry (AP-MS) has become the method of choice for identifying protein-protein interactions. However, conventional AP-MS studies provide information on protein interactions, but the organizational...
