Studies on Albuminemia “Fast Type”

Abstract

There are at least two types in double albuminemia. The one group named “Fast type” has higher mobility than normal albumin, and the other group named “Slow type” has the lower mobility in electrophoretic pattern.
In this paper, a family of the double albuminemia was reported.
Two years old boy who visited the 2 nd Dept. of Surgery of Nigata University Hospital, his mother and his uncle of mother side showed “Fast type” of double albuminemia.
The comparative studies on the “Fast type” albumin to normal person showed no significant difference in their immunogenecity.
It was observed that the molecular weight of “Fast type” albumin showed similar to that of normal albumin by SDS-Disc electrophoresis. The amino acids analysis of “Fast type” albumin was performed, and the composition of the “Fast type” albumin was compared with that of normal albumin and the pre-albumin of human serum to find rather low percentage in Lysin portion.
