Abstract

The ability to identify interactions between proteins is critical to understanding cellular processes. However, many of the complexes are transitory in nature, with half-lives of seconds or less. While important, these complexes are difficult to isolate as washing-based co-immunoprecipitation often results in inadvertent dissociation. Here, we present a technology for isolating complexes in a nearly instantaneous manner. Complexes are bound to paramagnetic particles (PMPs) and drawn through a barrier of immiscible liquid, thus purifying the complex from the bulk sample in a single step. Using model system, we have demonstrated the benefit of this method over traditional protocols.
