A packed bed anion exchange chromatography (PB-AEC), SepFastTM Supor Q pre-packed column, was used to purify NP(Δc375) from clarified feedstock. Hepatitis B is a small enveloped DNA virus that poses a major hazard to human health. The crystal structure of the T = 4 capsid has been solved at 3.3 A resolution, revealing a largely helical protein fold that is unusual for icosahedral viruses.

Viruses are classified based on their core genetic material and capsid design. (a) Rabies virus has a single-stranded RNA (ssRNA) core and an enveloped helical capsid, whereas (b) variola virus, the causative agent of smallpox, has a double-stranded DNA (dsDNA) core and a complex capsid.

The capsid appears like a long tube with the genome inside it. Figure 1. Viruses are classified based on their core genetic material and capsid design.

The helical capsid, exemplified by tobacco mosaic virus, is easiest to describe (Figure 1). The capsid is a large multimer of a single type of polypeptide enclosing the RNA genome in a groove.

Some viruses, especially bacteria infecting viruses (bacteriophages), have complicated capsid structures.

They are more common among viruses that infect plants, though influenza, measles, mumps, and rabies viruses all have helical capsid structures. Helical viruses. Naked helical viruses • Long rods • The capsid is cylindrical with helical structure (Tobacco mosaic virus) Enveloped helical viruses • Helical nucleocapsid placed within an envelope (influenza) Polyhedral viruses • The capsid is a regular polyhedron with 20 triangular faces (Poliovirus) capsid cores are proteinaceous containers that self-assemble to encase the viral genome and a handful of proteins that promote infection.

The majority of the viruses have capsids with either helical or icosahedral structure. Some viruses, such as bacteriophages , have developed more complicated structures due to constraints of elasticity and electrostatics. Start studying Virusintroduktion + Viral genetik (G.R och R.N).

Plant viruses showing helical capsid symmetry are used as a versatile platform for the presentation of multiple copies of well-arrayed immunogenic antigens of various disease pathogens. Helical PVNs are non-infectious, biocompatible, and naturally immunogenic, and thus, they are suitable antigen carriers for vaccine production and can trigger humoral and/or cellular immune responses.
