Design of Experiments (DoE), also called experimental design, is a statistical approach to process development that has gained wide acceptance in the biopharmaceutical industry. DoE is used to reduce development costs by speeding up the design process and to optimize the parameters of a particular step in the manufacturing process. The data presented here demonstrate the optimization of the CaPure-HA elution using a DoE approach.

Following publications discussing the impact of pressure interruptions on the retention levels of virus filters, an increased focus is being placed on filter users’ own risk mitigation strategies. Users are increasingly requesting technical guidance and support with viral validation from filtration experts, as part of their overall product support package. This guidance document provides a high level of assurance to filter users by demonstrating how combining robust virus clearance technology with the use of standard operating procedures can assure a…

With many pharmaceutical processes requiring large volumes of water, it is critical that any pharmaceutical-grade water used is protected from particulate or microorganism contamination, in order to ensure that process operations do not become inadvertently contaminated. Several approaches can be used to ensure that water remains free from contamination, including the storage of purified water or WFI (Water For Injection) at a minimum temperature of 80°C to discourage microbial growth in the storage system. Another approach is to add ozone,…
