【摘要】 研究了高效毛细管区带电泳分离人血清蛋白质的电泳行为及实验条件 ,建立了分离血清蛋白质的高效毛细管区带电泳法。血清样品经硼酸缓冲液 (5 0 mmol/L,p H8.80 )稀释后 ,以 0 .1 mol/L硼酸缓冲液 (p H9.3 5 ,含4g/L PEG80 0 0 )为电泳介质 ,在 5 0 μm i.d.× 3 7cm弹性石英毛细管柱 (有效柱长为 3 2 cm)中进行电泳分离 ,以2 0 0 nm紫外波长检测。方法简便、快速、重复性好 ,1 2 min内便可完成对血清中蛋白质的电泳分离。更多还原

【Abstract】 A high performance capillary zone electrophoretic method has been developed for the separation of proteins in human serum. Sera were diluted with a buffer (0.05 mol/L boric acid, pH 8.80), and then introduced hydrodynamically into a 37 cm(32 cm to detector)×50 μm i.d. fused\|silica capillary, electrophoresed for 12 min using a boric buffer solution (0.10 mol/L, pH 9.35; containing 4 g/L of polyethylene glycol 8000), and detected at the wavelength of 200 nm. The method is simple, rapid and repeatable.更多还原
