Abstract
The effect of storage of serum upon the paper electrophoretic protein fractions has been studied for 9 days. There were not found any significant differences between the sera stored at room temperature (15°C) and 0°C, if kept aseptically. However, trail on the electopherogram tends to appear more intensely by storage, therefore, in these cases, it is necessary to eliminate the trail effect in the quantative clensitometry as described in the previous paper.
