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.

Direct measurements of in situ interactions of rat brain opioid receptors with the guanine nucleotide-binding protein Go.

Georgoussi Z, Carr C, Milligan G

The interactions of rat brain cortical opioid receptors with the guanine nucleotide-binding protein (G protein) Go were probed in membranes by examining the ability of selective antipeptide anti-G protein antisera to disrupt receptor-G protein interactions. This was measured both by antibody-induced alterations in the characteristics of agonist binding to mu and delta receptor binding sites and by antibody attenuation of ... [more]
