Cell communication insights, 5, 1-7 (2014-05-20)
Protein-protein interactions play a pivotal role in both inter- and intra-cellular signaling. Identification of signaling protein complexes can thus shed important new insights into cell communications. We developed a parallel affinity precipitation protocol to overcome the disadvantages of the tandem...
