New Adenovirus Findings Has Been Reported by Investigators at University Nova of Lisboa

June 17, 2014

By a News Reporter-Staff News Editor at Virus Weekly -- Researchers detail new data in Adenovirus. According to news originating from Caparica, Portugal, by NewsRx correspondents, research stated, "The impacts of quaternary amine ligand density and matrix structure, namely hydrogel grafted and directly grafted, on state-of-the-art chromatographic membranes operated in bind-and-elute mode were evaluated for the purification of adenovirus serotype 5. The experiments were performed on a 96-well plate membrane holder, which is a convenient high-throughput screening tool for obtaining the best operating conditions for a process yield optimization. The results show that the hydrogel-grafted membranes are more suitable for virus purification than the directly grafted ones."

Our news journalists obtained a quote from the research from the University Nova of Lisboa, "By reducing the number of grafted ligands to low (1.7 mu mol/cm(2)) or medium (2.4 mu mol/cm(2)) density, it is possible to increase the recovery of purified virus by 60% compared to a highly charged membrane (3.3 mu mol/cm(2)) that yielded a recovery rate lower than 30%. In the reported experiments, Sartobind() Q, chosen as benchmark comparison, provides a better compromise between high recovery and large dynamic binding capacity."

According to the news editors, the research concluded: "Overall, this work contributes to the understanding and development of new membrane adsorbers specifically designed for virus purification."
