Abstract
The wall of the bulbus arteriosus and of the ventral aorta of trout ( Salmo gairdneri ) and salmon ( Salmo salar ) is characterized by a high elastin content, with an elastin:collagen ratio exceeding 2.5:1. The elastin, which displays an amino acid composition widely at variance with that of the mammalian protein, is present as 250-Å-diameter fibrils which have a strong affinity for electron-dense cations and which form in the intercellular matrix an isotropic reticulum. As in mammalian elastin, the fibrils can be resolved in negatively contrasted preparations into constituent primary filaments of about 25 A in diameter, aligned with an equatorial periodicity of about 55 Å.
