Purity by Design

by , , , , and

After launching Nereus LentiHERO, a game changing fit-for-purpose solution for lentiviral vector purification in 2022, Astrea Bioseparations present this end of year report with a selection of interviews, application notes, and articles. Identifying the gaps in lentiviral purification, they discuss how to increase processing efficiency, purity, and recovery of LVV particles. They also look towards the future to bring a radical change in bioprocessing for cell and gene therapies. The Nereus LentiHERO spin column is the first product in a…

Effective Processing of Lentiviral Vectors: Introducing a Paradigm-Shifting Technology

by , and

Therapeutic developers face significant challenges in purifying cell and gene therapies (CGTs). Current technologies for laboratory-scale lentivirus (LV) feedstock preparation are inefficient and not fit for purpose. From the benchtop to the clinic, all stages of CGT development require new solutions that break away from the current paradigm of biopharmaceutical manufacturing. Nereus LentiHERO nanofiber-based technology can address difficulties associated with purifying large and fragile modalities. Here, experts from the viral vector team at Astrea Bioseparations discuss how Nereus LentiHERO technology…

Purity By Design

by , , , and

Astrea Bioseparations has a well-established modular program to support customer projects from small to large scales with ligands, adsorbents, and chromatography columns that design purity into each process. Demand for increased productivity in biopharmaceutical manufacturing has placed new pressure on downstream purification operations. For recombinant proteins and monoclonal antibodies (MAbs), such pressure stems from significant gains in upstream productivity, particularly from high titers produced using increasingly efficient cell-culture systems. For viral vectors used in gene and gene-modified cell therapies and…

Reducing Cell and Gene Therapy Development Time and Cost with New Purification Strategies

by

The past 40 years have ushered in the most advanced medicines the world has ever seen, with tremendous improvements in biomanufacturing technologies to enable their development. Advances in production technology have brought significant improvements in upstream productivity, which then caused bottlenecks in downstream processing. Although many bottlenecks have been resolved for most biologics, new modalities such as gene therapies and mRNA vaccines are driving the need for differentiated purification solutions. Meanwhile, pressures to increase efficiency and reduce costs continue to…
