Structure of properdin oligomers (IMAGE) Aarhus University Caption To describe the structure of properdin oligomers, the researchers used two independent techniques. In the panels with a dark background, the properdin molecule is seen as a light triangular molecule with an "eye" in each corner. This image was obtained by electron microscopy. The panels with a light background show the corresponding results obtained with small angle scattering. The results from the two independent techniques fit surprisingly well with each other.
