Affinity Capture-MS

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner is identified by mass spectrometric methods.

Ephrin-As, Eph receptors and integrin ?3 interact and colocalise at membrane protrusions of U251MG glioblastoma cells.

Makarov A, Ylivinkka I, Nyman TA, Hyytiaeinen M, Keski-Oja J

Glioblastoma is the most common brain cancer. Ephrins and their Eph receptors play important roles in the development of central nervous system and the regulation of cancer cell migration and invasion. In a search for the Eph receptor complexes, we used tandem affinity purification based interaction screening with tagged ephrins A1, A3 and A4 combined with protein identification by mass-spectrometry ...

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.
