Gaining a license can be a complex process, but a few key tips can help you avoid common pitfalls and patent infringements.

How to reduce plasmid-mediated metabolic burden for higher yields.

Automated in-line dilution can help solve capacity, financial, and quality concerns that biopharmaceutical manufacturing plants may be facing.

To assess current trends in fermentation and cell culture equipment, BioPharm International turned to Geoff Hodge, managing director of process technology, Xcellerex, Inc.; Günter Jagschies, senior director of strategic customer relations, life sciences, biotechnologies, GE Healthcare; and Rich Mirro, product manager, New Brunswick Scientific.

To select the right partner for media design and optimization services, several key factors must be considered.

Select the best approach to determine critical quality attributes.

Companies often wait for a critical mass before adopting new technologies. But if no one takes the risk, critical mass will never be reached.
