Preparation of Novel Macroporous Silica Based Amide Polymer Bonded Packing and Its Application to the Separation of Proteins
新型大孔硅质酰胺型聚合物键合相的制备及其对蛋白质的分离

A novel macroporous silica based amide polymer bonded packing for protein separations in HPLC is described.The macroporous silica support was bonded with diethoxymethyl vinyl silane and then copolymerized with methylacrylamide and divinylbenzene to produce a tailored stationary phase with high resolution and inertness.The repeatability of packing preparation is good.They were characterized through the application of a standard protein mixture of pepsin,glucose oxidase,bean trypsinogen inhibitor and ribonuclease.The time for elution of these proteins is less than 12 minutes.It is suggested that the macroporous silica based amide polymer bonded packing can be used to quickly separate biopolymer.This packing is a better alternative for the biopolymer separation.
