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.

In vivo assembly of coatomer, the COP-I coat precursor.
Coatomer, a seven-subunit hetero-oligomeric complex, is the major component of the COP-I membrane coat of transport vesicles of the early secretory pathway. We have followed the assembly of this complex in vivo by pulse-chase experiments and immunoprecipitation of native coatomer subunits and found that it is an ordered process that takes 1-2 h to complete. During assembly, direct interactions between ... [more]
