Isolation of a Urinary Mucoprotein Capable to Precipitate Oxalate
Mucoproteins are components of urinary stones. Some authors had suggested that these components promote stone formation1, 2. We have shown the promoting effect of the stone mucoproteins on oxalate precipitation3. The calcium concentration appears to play an important role in the mineral-mucoprotein interaction4. This paper presents evidence on the isolation and some of the physicochemical properties of a mucoprotein from stone former urine. The material binds calcium and phosphate and promotes oxalate precipitation.
