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.

As part of an ongoing effort led by Steve Gygi, Wade Harper, and Ed Huttlin in the Department of Cell Biology at Harvard Medical School, we are systematically profiling the interactions among human proteins using affinity purification mass spectrometry. In this effort, HA-tagged bait proteins obtained from the human ORFeome collection (version 8.1; Marc Vidal) are expressed individually in human ... [more]

Affinity Capture-Western
Affinity Capture-Western

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.
