Abstract
On starch-gel or polyacrylamide-gel electrophoresis of human serum, a supernumerary zone of aspartate aminotransferase activity may be demonstrated, migrating with the slow alpha(2) protein zone. This appearance is due only to cationic aspartate aminotransferase, bound by alpha(2)-macroglobulin. The binding is strongly potentiated by dilute borate buffers.
摘要
在人血清的淀粉凝胶或聚丙烯酰胺凝胶电泳中，可能会显示出一个额外的天冬氨酸转氨酶活性区带，它与缓慢移动的α₂蛋白区带一起迁移。这种现象仅由与α₂-巨球蛋白结合的阳离子天冬氨酸转氨酶引起。稀硼酸盐缓冲液可强烈增强这种结合。
