Abstract:
:A purification scheme based on hydrophobic interaction chromatography was developed to separate inactivated foot-and-mouth disease virus (FMDV) from crude supernatant. About 92% recovery and 8.8-fold purification were achieved on Butyl Sepharose 4 FF. Further purification on Superdex 200 resulted in another 29-fold purification, with 92% recovery. The columns were coupled through an intermediate ultrafiltration unit to concentrate the virus. The entire process was completed in about 3.5h, with 75% final FMDV recovery, and 247-fold purification. The final product had purity above 98%, with over 99.5% of host cell DNA removed. High-performance size exclusion chromatography (HPSEC), Western blot, dynamic light scattering (DLS), and transmission electron microscopy (TEM) indicated that the purified virus contained the required antigen, and was structurally intact with a spherical shape and a particle size of 28 nm.
