An immunoaffinity matrix was prepared using human polyclonal antibody (Intragam) attached to Sepharose 4B activated with CNBr. The immunoaffinity matrix was then assessed with regard to its capacity to remove viruses. The challenge virus, poliovirus type 1 was loaded in high titre in either PBS or a preparation derived from human plasma known as supernatant II + III. This fraction is depleted of IgG and is used to prepare human albumin. It was shown that an average greater than 5 logs of spiked virus were removed in one passage through the column. This type of approach may prove useful as a viral removal method in biopharmaceutical manufacturing.

Immunoprecipitation01:20

Immunoprecipitation

Immunoprecipitation, or IP, is a widely used technique that employs protein-antibody interactions to isolate proteins or protein complexes in their native state for studying protein-protein interactions, quaternary structures, or supramolecular complexes. Various modifications of the technique, including chromatin IP, cross-linking IP, and fluorescence IP, are commonly used.

Types Of Column Chromatography

The stability and compatibility of column material with samples are crucial for efficient purification in chromatographic techniques. Various operating parameters such as pH, temperature, or solvent affect the packing of the column material, thereby determining the purification efficiency. The choice of column material also plays an essential role in deciding the operating parameters and can be modified based on the proteins that need to be purified.

Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
