Cartilage oligomeric matrix protein was isolated in the native state from the Swarm rat
chondrosarcoma. A crucial step was its selective extraction with EDTA-containing buffer. The
purified protein was subjected to electron microscopy using rotary shadowing and negative
stain. The images allowed the construction of a structural model. The bouquet-like protein
consists of five 28-nm-long arms containing a peripheral globular domain, a flexible strand,
and a central assembly domain, where the five arms meet in a cylindrical structure.
