Negative-Stain Electron Microscopy Images of IgM and AIM

Caption

Electron microscopes and modern computer image processing allowed University of Tokyo researchers to uncover the correct structure of a protein essential in the immune system, IgM, and a much smaller protein that is bound inside, AIM. IgM is the larger, incomplete hexagon shape and AIM is the smaller broad bean shape inside the wedge-shape gap. In the right-side image, AIM is more easily recognized as the bright white, broad-bean-shaped spot.
