A high resolving capacity of agarose gel in electrophoretic separation of blood serum proteins permits the isolation of 7 or 8 fractions instead of 5 routinely isolated by paper or acetate cellulose film electrophoresis. The strips on proteinograms obtained using Beckman Paragon device are identified. The authors emphasize that reference values should be determined for each laboratory and present the proteinograms of 80 normal subjects they obtained. If M-gradient appears on the proteinogram, the zone of its localization should be specified in comments.
