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.

Transcriptomic alterations upon nuclear XIAP overexpression reveal IGFBP6/Wnt as a regulatory axis in breast cancer cell survival and chemoresistance.

X-linked inhibitor of apoptosis protein (XIAP) is an antiapoptotic protein which plays canonical functions in the cytoplasm. However, we have previously demonstrated that nuclear XIAP is associated with increased cell growth and drug resistance as well as unfavorable outcomes in breast cancer. Therefore, this work aimed to investigate the non-canonical molecular functions associated with abnormal XIAP nuclear localization in breast ... [more]

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.
