Co-immunoprecipitation (Co-IP) (followed by immunoblotting) is a technique widely used to characterize specific protein-protein interactions. Investigating interactions of proteins containing "sticky" polyalanine (PolyA) tracts encounters difficulties using conventional Co-IP procedures. Here, we present strategies to specifically capture proteins containing these difficult PolyA tracts, enabling subsequent robust detection of interacting proteins by Co-IP.
