在市售设备上使用连续洗脱聚丙烯酰胺凝胶电泳(CE-PAGE)在6小时内分离出毫克量的聚合度为4 - 32的肝素寡糖。通过强阴离子交换高压液相色谱、电喷雾离子化傅里叶变换质谱和二维核磁共振光谱证实了CE-PAGE分离的寡糖的纯度和结构完整性。所描述的方法是直接和时间效率,提供大小均匀的寡糖,可用于测序,蛋白质结合,和其他结构-功能关系的研究。
Separation of milligram amounts of heparin oligosaccharides ranging in degree of polymerization from 4 to 32 is achieved within 6 hours using continuous-elution polyacrylamide gel electrophoresis (CE-PAGE) on commercially available equipment. The purity and structural integrity of CE-PAGE-separated oligosaccharides are confirmed by strong-anion exchange high-pressure liquid chromatography, electrospray ionization Fourier transform mass spectrometry and two-dimensional nuclear magnetic resonance spectroscopy. The described method is straightforward and time-efficient, affording size-homogeneous oligosaccharides that can be used in sequencing, protein binding, and other structure-function relationship studies.
