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。
