P2X receptor subunits (P2X1 to P2X7) assemble to form trimeric homomers or heteromers. Here, we describe the use of protein cross-linking to study the composition of P2X receptor complexes. This simple protocol is useful for determining the stoichiometry of P2X heteromeric receptors as well as for assessing the effect of point mutation, truncation, or concatenation on the quaternary architecture of these receptors.
