Continuous purification of a parvovirus using two aqueous two‐phase extraction steps
Biotechnology Progress, EarlyView.Abstract Aqueous two‐phase systems (ATPS) are a liquid–liquid extraction method that offers low‐cost, continuous‐adaptable virus purification. A two‐step ATPS using polyethylene glycol (PEG) and sodium citrate that recovered 66% of infectious porcine parvovirus with 2.0 logs of protein removal and 1.0 logs of DNA removal in batch has now been run ...

Advances in protein subunit vaccines against H1N1/09 influenza
Frontiers in ImmunologyThe A/H1N1pdm09 influenza virus, which caused the 2009 pandemic, has since become a recurring strain in seasonal influenza outbreaks. Given the ongoing threat of influenza, protein subunit vaccines have garnered significant attention for their safety and

Minimizing batch‐to‐batch variability of a live virus vaccine by process analytical technologies
Biotechnology Progress, EarlyView.Abstract For bioprocesses producing live virus, such as enterovirus Coxsackievirus A21, viral titer (infectivity basis) decay rates can exceed 30% within a day. Consequently, harvest timing is paramount. To optimize titer at harvest, a continuous viral product titer model was generated to elucidate kinetics.

Harvesting AAV by tangential flow filtration using reverse asymmetric membranes
Biotechnology Progress, EarlyView.Abstract Efficient bioreactor clarification for harvesting virus particles is often challenging. Tangential flow filtration is attractive as it can be easily adapted for batch and perfusion operations. Here the feasibility of using reverse asymmetric hollow fiber membranes, where the more open support structure faces the feed stream, has been ...

core
Chemistry &Biodiversity, EarlyView.ABSTRACT The subfamily Gomphrenoideae is composed of about 480 accepted species, many of which have been historically used as medicinal plants, reason why they have been studied in terms of chemical profile, biological activity, and safety. This review consolidates the advances in research on this subfamily over the past 47 years, emphasizing its ...
