Purification protocols of the viruses: HIV-1, Lassa virus, oncornavirus and other retroviruses. Protocol uses an iodixanol gradient in a sedimentation velocity mode to purifyHIV-1 virions without affecting the infectivity of the virus. In rate-zonal iodixanol gradients the HIV-1 was effectively separated both from Vif and from the microvesicles. - [Read M5 Velocity (rate zonal) gradients for purification and assembly analysis of viruses.]
Unlike spherical phage, such as T4 and λ, which have roughly equal weight ratios of protein to DNA, filamentous phage have about six times more protein than DNA; the protein therefore contributes substantially to the absorption spectrum.
