抄録

At least 4 isoforms of intestinal alkaline phosphatase (ALP) have been identified in human, which are common intestinal ALP, intestinal ALP variant, blood group-dependent high-molecular intestinal ALP, and fetal intestinal ALP. These isoforms can be clearly separated by polyacrylamide gel electrophoresis (PAGE). However, comparative studies on electrophoretic mobilities of these isoforms which are separated by cellulose acetate membrane and agarose gel have not been done yet. On the cellulose acetate membrane electrophoresis, a relatively tightened band of intestinal ALP variant may be presented at the position of liver/bone ALP (α22β position) and a broad band of the blood group-dependent high-molecular intestinal ALP may be exhibited at the position overlap from bone ALP to common intestinal ALP (α2β-β position). On the agarose gel electrophoresis, a tightened band of the intestinal ALP variant and/or the blood group-dependent high-molecular intestinal ALP was possible to detected around bone ALP (α2β position).
