Automation of Microbioreactors

Current methodologies in genetics and microbiology enable researchers to influence metabolic pathways of microbial cells in many directions. Beside the academic interest in investigating fundamental functions in metabolic pathways, commercial production of valuable compounds by microbial hosts is state of the art. For example, such products include enzymes (lipases, proteases, phytases), therapeutic agents (insulin, antibodies), bulk chemicals (lysine, glutamate, citric acid), or the microbial cells themselves (used in brewing or milk processing), with therapeutic agents probably the fastest growing market.…

Moving Forward with a Gene Therapy for Damaged Hearts

A cocktail of three specific genes can reprogram cells in the scars caused by heart attacks into functioning muscle cells. Adding a gene that stimulates the growth of blood vessels enhances that effect, say researchers from Weill Cornell Medical College, Baylor College of Medicine, and Stony Brook University Medical Center in a report that appears online in the Journal of the American Heart Association (1). “The idea of reprogramming scar tissue in the heart into functioning heart muscle was exciting,”…

Standards for Ancillary Materials Used in Cell- and Tissue-Based Therapies

Cell- and tissue-based therapies are being used increasingly to treat many diseases for which currently no other adequate treatment options are available. These products contain human or animal cells that can replace, regenerate, or augment a recipient’s diseased, dysfunctional, or injured cells, tissues, or organs. Cells or tissues might be unmanipulated, or their biological characteristics can be altered ex vivo before administration of the final product to patients. Examples of cell therapies range from traditional blood transfusions to recent approaches…

Upstream Processing

The “Cell Culture and Upstream Processing” track began many years ago as a conference of its own. In October 2004, IBC Life Sciences brought it together in Boston, MA, with three other events (“Recovery and Purification,” “Production and Economics,” and “Scaling Up from Bench to Clinic”) to create the first BPI Conference. Just like BPI magazine’s editors, the event producers have depended on industry advisors from the beginning. Our editorial advisory board (EAB) members give generously of their time and…

Enlightening Results

Separating spectroscopy from spectrometry is not as straightforward as it might seem. Spectroscopy is the science of the interactions between matter and radiated energy, and spectrometry is the technology that applies that science (1). The former generates no results on its own. It is concerned with spectra produced when matter interacts with or emits electromagnetic radiation, including all methods of producing and analyzing light spectra using spectroscopes, spectrographs, spectrometers, and spectrophotometers. The distinction should come from the meanings of the…

Fujifilm Diosynth Biotechnologies

One of the major bottlenecks in the production of biopharmaceuticals is the efficient expression of therapeutic proteins in microbial or mammalian cells. The Escherichia coli pAVEway™ expression system described here has been developed to ensure high product titers and efficient scale up to GMP manufacture while minimizing many common issues seen in other expression systems, such as “leaky” expression (expression of recombinant protein in the absence of inducer). How It Works The use of a number of powerful E. coli…

Purification of Oligonucleotides on TOYOPEARL GigaCap® Q-650S

TOYOPEARL GigaCap Q-650S high capacity, high resolution anion-exchange resin for process scale applications was recently introduced by Tosoh Corporation. This resin, with dynamic binding capacities (DBCs) approaching 190 g/L for bovine serum albumin (BSA), is the newest member of the TOYOPEARL® product line. TOYOPEARL GigaCap Q-650S maintains the high capacity of our popular TOYOPEARL GigaCap Q-650M, and the 35 µm particle size provides high resolution for improved separation of process impurities and aggregates. Introduction The purification of oligonucleotides using anion…

High-Performance Biopharmaceuticals Manufacturing

Identifying the most appropriate contract manufacturer that is most likely the best match for your lead pharmaceutical candidate is a true challenge. Rentschler is a biopharmaceutical manufacturer with over 35 years proven track record. Focused on mammalian cell lines, our experience covers the development, production, and aseptic filling of recombinant proteins such as cytokines, enzymes, monoclonal antibodies, and fusion proteins in compliance with international GMP standards (EMA/FDA). We don’t just claim to be reliable and experienced; our many successful projects…
