近年来发现动脉粥样硬化的发生率与血清HDL水平之间呈负相关。因此对HDL及其中载脂蛋白的结构,功能和代谢的研究兴趣大为增加。进行以上研究需要较大量的纯净样品。以往分离血清HDL多采用多次分步超速离心上浮或以密度梯度在水平头中 In recent years, the incidence of atherosclerosis was found to be negatively correlated with serum HDL levels. There has therefore been an increased interest in the research of HDL and the structure, function and metabolism of apolipoproteins therein. The above study requires a large amount of pure samples. Separation of serum HDL in the past to use multiple step-speed ultracentrifugation floating or density gradient in the level head
