Cleaning Polyethersulfone Membranes After Ultrafiltration-Diafiltration in Monoclonal Antibody Production

In the pharmaceutical industry, ultrafiltration (UF) membranes are used extensively in the downstream purification of recombinant proteins or monoclonal antibodies. However, the fouling of membranes after a unit operation?especially when recombinant proteins or monoclonal antibodies are highly concentrated?is a common problem. Typically, normalized water permeability (NWP) of a membrane can be reduced to about 20 percent of its original permeability at the end of an ultrafiltration-diafiltration (UF-DF) operation.

Licensing

Historically, the big pharmaceutical companies (Big Pharma) have sought to feed their marketing machines by manufacturing blockbuster drugs—chemical-based, one-type-fits-all products that treat chronic conditions such as heart disease or arthritis. This approach has yielded recurring revenue streams from large patient populations. In contrast, biotechnology companies typically have created protein-based drugs,or biologics, to treat acute or niche conditions and diseases. With few exceptions (such as the biotech giant Amgen), biotech companies have foregone doing the marketing and sales of their drugs themselves, and have, instead, relied on others to perform their marketing and sales functions.

Efficiency Measurements for Chromatography Columns

Misinterpreting the effluent profiles obtained during tracer measurements performed for determining packing quality can often lead to excessively large percolation velocities and exaggeration of packing problems. Highly useful and reliable information can be obtained through characterization of tracer effluent curves using the method of moments, information that could be critical for successful scale-up of chromatographic steps. This is the sixth in the "Elements of Biopharmaceutical Production" series.
