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.

Aggregates of green fluorescent protein (GFP)-fused truncated N-terminal huntingtin containing abnormally long polyglutamine tracts (150 repeats of glutamine residue) were purified from an ecdysone-inducible mutant neuro2A cell line (HD150Q-28) by using a fluorescence-activated cell sorter. To analyze the aggregate-interacting proteins, we subjected the purified aggregates to SDS-PAGE; prominent protein bands in the gel were digested with Achromobactor lysyl endopeptidase, followed ...

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.
