The evaluation of lipid electropherograms obtained by electrophoresis in agarose gel is sometimes difficult owing to methodological errors, e. g. the artificial mal-formation of individual lipoprotein bands. It was shown that this "edge zoning effect", e. g. resulting from broadened bands with irregular boundries, can be abolished by the addition of EDTA (0,36 g/l buffer) to the gel.
由于方法学上的误差，例如个别脂蛋白条带的人为畸形，通过琼脂糖凝胶电泳获得的脂质电泳图的评估有时会很困难。结果表明，这种“边缘分区效应”，例如由边界不规则的宽带引起的，可以通过向凝胶中添加EDTA（0.36 g/l缓冲液）来消除。
