Time to market, resource requirements, cost, and flexibility are key considerations in designing purification processes suitable for manufacturing biopharmaceutical products. Over the past decade, many advances have been achieved in disposable processing systems that have allowed for increased processing at a lower cost. That is in part attributable to reductions in necessary resources, changeover costs, and cleaning-validation requirements. Large-scale, prepacked chromatography columns have recently become available for clinical and commercial manufacturing, and they represent a growing trend in the industry.…
