TL;DR: Atomic force microscopy is utilized coupled with other methods to reveal time- and concentration-dependent stoichiometries and conformations of assembling human MutSα–MutLα–DNA complexes, and it is found that they assemble into multimeric complexes comprising three to eight proteins around a mismatch on DNA.
