Tandem affinity purification (TAP) tagging is a method to purify multimeric protein complexes that can be used under essentially physiological conditions. This technique allows subsequent protein identification by mass spectrometry or functional analysis of the proteins post-purification. The TAP method has already been used to help elucidate large networks of interacting proteins in several organisms.
