Abstract

We have been able to amplify the lysine binding pocket region of human apo(a) kringle type 5 starting from the DNA isolated from peripheral blood lymphocytes. This development now permits the identification of Lp(a) mutants that by lacking their ability to bind to lysine/fibrin would have a lesser thrombogenic potential.

摘要

我们已经能够从外周血淋巴细胞分离的DNA开始,扩增人载脂蛋白(a)5型kringle结构域的赖氨酸结合口袋区域。这一进展现在使得能够鉴定出脂蛋白(a)突变体,这些突变体由于缺乏与赖氨酸/纤维蛋白结合的能力,其血栓形成潜力较小。
