Preparation of Novel Microspheres for Protein / Vaccine Separation Application
Polysaccharide particles such like agarose particles have been widely used in protein separation and purification as chromatographic packing materials by biological scientists and in industry. However, the limitation of conventional agarose particles is that the separation resolution is limited due to their broad size distribution. Furthermore, the particles with large size are usually used for industrial separation and purification to avoid the increase of back-pressure, which also limit the separation resolution. On the other hand, the particulate vaccine such like virus-like particle (VLP) has attracted more and more attention, conventional agarose particles with small pore size not only limited the adsorption of VLP, but also enhanced the disassociation of VLP, resulting very low activity recovery of VLP.We have developed a novel membrane process to prepare uniform agarose particle. By this technique we can control the CV (coefficient of variation) value which representing the size distribution around 15%, and we can prepare small uniform particles with high agarose concentration. Therefore, we can use small particles instead of large particles, and increase the separation resolution and flow rate of chromatography.  We have developed a new process to prepare giga-porous particle with pore size controllable between 100nm to 500 nm, and we found that it not only increased the loading amount of VLP, but also avoided the disassociation of VLP. This was because large pore size weakened the multi-site interaction between VLP and pore. This novel particle has been used for production of particulate vaccine instead of ultra-high speed centrifugation technique, much higher recovery was achieved.
