Dorsalis by salting out, ion exchange chromatography, and gel filtration chromatography. By salting out the egg homogenate, SDS-PAGE analysis revealed that the Vns were mainly precipitated in a 50~70% ammonium sulfate solution. The salted-out proteins were further purified by ion exchange chromatography, and the result showed that Vns were mainly eluted with a 0.3~0.5 M sodium chloride gradient. Finally, the elutes of ion exchange chromatography were refined by running them through gel filtration chromatography to obtain purified Vns. SDS-PAGE separated the 48- and 51-kDa purified Vns, and used them as antigens to raise polyclonal antibodies.

利用硫酸铵盐析法初步分离果实蝇卵中的蛋白质，以SDS-PAGE蛋白质电泳分析得知，卵黄蛋白主要在硫酸铵溶液浓度为50~70%时被沉淀出；盐析沉淀所得之卵黄蛋白，再以离子交换层析法进一步纯化显示，卵黄蛋白主要会在0.3~0.5 M氯化钠的浓度范围间被析出来；再将析出液浓缩后，经凝胶过滤层析法做最后的纯化，即获得纯化之卵黄蛋白。

We found that the microstructures and magnetic properties were not influenced with depositing temperature and sputtering power. The magnetic properties were only affected by Fe layer thickness. When the Fe layer thickness is thinner than 5 nm, weak exchange coupling raised between Fe cap layer and FePt recording layer. When the thickness reached 10 nm, the strongest exchange coupling formed. Film coercivity didn't distinctly vary as Fe layer thickness is thinner than 15 nm. Consequently, we measured DCD curves and had the same conclusions. Indeed, the appearance of exchange coupling is confirmed with 10 nm Fe cap layer.

我们并发现溅镀Fe之温度与瓦数，并不会对结构或是磁性质有显著的影响，Fe厚度的改变虽然也不会改变结构，但是对Cr/Pt/FePt/Fe磁性质却有明显的变化，当Fe厚度薄时(3、5 nm)，在Fe和FePt界面仅有弱的交换耦合力产生，Fe厚度是10 nm时，此时交换耦合力为最强，厚度再增加到15、20 nm时，Hc反而略为上升，同样的我们量测DCD曲线，也证实了Fe厚度10 nm的确有交换耦合力存在。
