Virus Isolation and Preparation of Sucrose-Banded Chikungunya Virus Samples for Transmission Electron Microscopy

Virus isolation and purification is an invaluable technique in virology to detect and characterize viruses. This chapter describes a large-scale Chikungunya virus (CHIKV) propagation and purification methods by using discontinuous sucrose gradient, and sample preparation for transmission electron microscopy. Sucrose-banding yields large quantities of high-titer (1010 pfu/ml) CHIKV stocks. Such stocks are stable for years when stored at −70 °C.
