Advances in peritoneal dialysis. Conference on Peritoneal Dialysis, 14, 120-123 (2000-01-29)
The presence of mixed disaccharides (maltose and isomaltose) in plasma from uremic patients has been previously investigated using gel-permeation chromatography. However, this method is unable to separate maltose (linked alpha-1-4) from isomaltose (linked alpha-1-6). We describe an alternative method using
