Increasing Efficiency and Throughput with Separation and PurificationIncreasing efficiency and throughput in downstream separation and purification performance is currently a major focus in the biopharmaceutical industry. Traditional TFF systems cannot be scaled in a linear fashion to meet the projected demand for fermentation and cell culture based products. NCSRT has created a patented line of filtration solutions that address the bottlenecks currently experienced as biopharmaceutical products scale up from clinical trials to blockbuster production quantities.

The Company at the Crossroads. Part 2: Build or Buy?When making critical decisions such as whether to build or buy critical capabilities, companies need a decision-making approach that weighs risks and rewards as a science with adequate inputs, repeatable processes, and measurable results. The method must also accommodate the human factor by encouraging wide participation and providing the kind of neutral decision criteria that satisfies participants about the objectivity of the process.

Disposable Process for cGMP Manufacture of Plasmid DNADisposables are increasingly being used in the manufacture of biopharmaceuticals. This article describes the design of a fully disposable process for the cGMP manufacture of clinical trial grade plasmid DNA. It addresses the rationale for implementing such a process with respect to the manufacture of patient-specific plasmid DNA vaccines for the treatment of leukemia. The process incorporates a number of disposable technologies, which are simple to use and thus reduce the need for investment in expensive equipment and cleaning validation.
