Scanning electron microscopy and electron probe microanalysis of calcified alpha-elastin coacervates.
The uptake of calcium and phosphorus from a serum calcification medium by coacervated alpha-elastin was studied by electron probe microanalysis and scanning electron microscopy. Calcium and phosphorus were bound by the coacervate in ratios similar to that of hydroxyapatite. A significant difference was observed in the secondary electron image of the coacercules from the serum during calcification of the coacervate.
