Also activated carbon adsorption and high-speedcentrifugation on the removal of the effect of Sepia melanin was compared.
实验结果表明：高速离心法去除黑色素方法优于活性炭吸附；
2
A fairly pure preparation can be obtained through two runs of low-speedcentrifugation and a single run of high-speedcentrifugation in sucrose gradient.
主要是经过两次低速离心，一次蔗糖梯度超速离心，即可得到一定纯度的细胞膜。
3
Conclusion: the preparing method of highspeedcentrifugation could replace the normal preparing method of water ethanol method.
