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.en© Springer Science+Business Media New York 2013Polyalanine tract; ARX; Co-immunoprecipitation; Protein–protein interactionBook chapter002013133010.1007/978-1-62703-438-8_92-s2.0-8488315858218338Mattiske, T.
