Abstract
New cellulose acetate membrane SELECA-VSP was prepared as a substitute for the conventional cellulose acetate membrane SEPARAX-SP, which has been widely used for serum protein electrophoretic fractionation. We evaluated the separating quality of this new membrane, using fully automated serum protein electrophoresis system AES630.Correlation of serum protein fraction values (percentage composition) between the two membranes, those patterns of sera from patients with protein disorders, and reference intervals in healthy adults were analyzed. In addition, the electrophoretic determinations of amylases and glycoproteins were tested.The correlation coefficients of the each electrophoretic fraction between SELECA-VSP and of SEPARAX-SP were greater than 0.97. Reference intervals in healthy adults on SELECA-VSP and on SEPARAX-SP were nearly equal.The separating performance of SELECA-VSP were rather higher as compared to SEPARAX-SP for serum protein electrophoretic fractionation, amylase isoenzymes and glycoproteins.The utility and effectiveness of a new membrane SELECA-VSP can be best appreciated on the basis of our experimental results.
