离子交换

In order to investigate the influence of membrane diffusivity on the charge-discharge performance of a single all vana- redox flow battery,the diffusion coefficients of VO~(2+) and VO_2~+ in two types of given ion exchange membrane s were measured with a specific designed permeation cell,the diffusion coefficients were about 10~(-9)～10~(-7) cm~2/s.

为了研究隔膜扩散特性对全钒氧化还原液流单电池充放电性能的影响，利用设计的渗透池实验测定了VO2+和VO2+在两种离子交换膜中的扩散系数，约为10-9~10-7cm2/s。

Objective To isolate,identify and purify the allergens in egg.Methods The albumen was extracted from the egg and the albumen from the vitellus.The total protein of the egg was isolated by SDS-PAGE.The allergens of egg were identified by Westernblotting.

Two kinds of DALF, DALFA and DALFB, was isolated in the DEAE-cellulose column using process elution method, SDS-PAGE analysis revealed the difference between the two eluates was the different ratio of H:L of the twenty four subunits.

通过离子交换层析柱(DEAE-52)分步盐洗脱技术，分离到两种不同分子量的蛋白质组分(DALF_A和DALF_B)，通过SDS凝胶电泳分析证明DALF_A和DALF_B不同之处在于蛋白壳的H和L亚基之间结合比例不同，由此形成释放铁动力学特性和铁核中的磷铁组成比也存在一定差异。

METHODS: The rhBMP-2,expressed in Escherichia coli, was washed by Triton X- 100 and further purified by DEAE chromatography.The inclusion bodies were resolved in 8 mol/L urea, and were refolded and dimerized in the redox systems (reduced and oxidized glutathione). Finally, a one - step purification procedure based on the heparin affinity chromatography was implemented. The biological activity of purified rhBMP - 2 were tested by induction of the alkaline phosphatase activity in C2C12 cells.
