Antibodies Measured Up

Antibodies are typically represented by a "Y"-shaped diagram. The two arms of the Y represent the epitope-binding regions. Antibodies are also generally believed to be 'small'. Shown here is an isosurface contour plot of an antibody (crystal structure, at the top) and a ~180 KDa collagen NC1 hexamer (bottom).
