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.

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.
