Abstract以连续自由流电泳的区带电泳模式分离血红蛋白和细胞色素C,比较了不同缓冲液甘油浓度下的分离效果,确定了最终装载在神舟4号飞船上A3—2型电泳仪的电泳分离条件,通过地面和空间实验,初步探讨了微重力对连续自由流电泳分离的影响,并对电泳的分离产物做了多种检测.
Other AbstractSeparation of two colored model proteins, cytochrome Cand hemoglobin, were conducted in the specially self-designed free flow electrophoresis device A3-2 using zone electrophoresis mode under 1 g-and fig-conditions. The results demonstrated that the higher resolution of free flow electrophoresis acquired under the micrograv-ity is obtained. Both onboard LBD detection and measurement of the separation by the spectrometer demonstrated that the distance between the zone maxima of the two proteins were increased and the dispersion of hemoglobin decreased. The exper-invents also included: (1) The effect of the glycerol concentration on the separation results;(2) Post-flight analysis of the contents of the fractions. The separation results of 10%,7%, 4%, 2% and 0% glycerol concentration in the electrophoresis buffer are compared and no significant effect of the glycerol on the separation results are found.So the glycerol and its disadvantages for the clean and storage of the device were excluded finally.Gel electrophoresis and mass spectrometry analysis of the contents of the fractions confirmed that two proteins have been effectively separated.
