Production- and Purification-Relevant Properties of Human and Murine Cytomegalovirus.

There is a large unmet need for a prophylactic vaccine against human cytomegalovirus (HCMV) to combat the ubiquitous infection that is ongoing with this pathogen. A vaccination against HCMV could protect immunocompromised patients and prevent birth defects caused by congenital HCMV infections. Moreover, cytomegalovirus (CMV) has a number of features that make it a very interesting vector platform for gene therapy.

Impact of complement and difference of cell-based assay and ELISA in determination of neutralization capacity against mumps and measles virus.

Neutralizing antibodies against mumps and measles virus are considered a correlate of protection against these diseases. Measurement of neutralizing antibodies is mostly performed using plaque reduction neutralization assay or 50% cell culture infective dose (CCID) neutralization assay, but there are attempts for measuring neutralizing antibodies using enzyme-linked immunosorbent assay (ELISA) which is simpler, but the literature data regarding its convenience are diverse. The role of complement and antibodies in neutralizing capacity of sera is not completely defined.

Quality-Related Properties of Equine Immunoglobulins Purified by Different Approaches.

Whole IgG antivenoms are prepared from hyperimmune animal plasma by various refinement strategies. The ones most commonly used at industrial scale are precipitation by sodium or ammonium sulphate (ASP), and caprylic acid precipitation (CAP) of non-immunoglobulin proteins. The additional procedures, which have so far been used for experimental purposes only, are anion-exchange (AEX) and cation-exchange chromatography (CEX), as well as affinity chromatography (AC) using IgG's Fc-binding ligands.

Streamlined downstream process for efficient and sustainable (Fab') antivenom preparation.

Background: Antivenoms are the only validated treatment against snakebite envenoming. Numerous drawbacks pertaining to their availability, safety and efficacy are becoming increasingly evident due to low sustainability of current productions. Technological innovation of procedures generating therapeutics of higher purity and better physicochemical characteristics at acceptable cost is necessary.

Biological Activities and Proteomic Profile of the Venom of ssp., a very Rare Karst Viper from Croatia.

The karst viper ( ssp.) favours high-mountain dry grasslands in southern and south-eastern Croatia. It is medically less important than other species, because of its remote habitat and the very small amount of venom that it injects by its relatively short fangs.
