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 ...
