Virus

The term chromatography refers a set of laboratory procedures used in the separation of mixtures. Chromatography can be especially useful in viral processing, which aims to stop the viruses in a specific sample from infecting the desired product. There are two most widely used methods of viral processing: viral removal and viral inactivation. Viral removal is a method where all the viruses are simply removed from a specific sample completely. The second method typically allows some viruses to remain in the final product, but alters the viruses to become non-infective.

Some of the common viruses removed by viral removal and viral inactivation are HIV-1 and HIV2, hepatitis A, B, and, C, and various parvoviruses. There are some cases, however, where the virus itself is the desired product of the process, as in the case of HIV research. In many cases, researchers are trying to extract the viruses from the blood samples for study, but not specifically for blood purification. These viral processing techniques are also commonly used to remove particles produced as a result of a viral infection.

Chromatography is especially useful in removing viruses, as well as purifying the protein present in the samples. Chromatographic techniques are also effective against all types of viruses, but the level of the removal of the virus is typically dependent on the column composition and the reagents used in the process. The effectiveness of chromatographic processes can vary greatly between different types of viruses, and this efficiency can change based on the buffer used in the process. One of the most common concerns in chromatographic processes in viral processing is the sanitation between batches whenever these processes are performed.
