The laboratory services provider is responding to growing demand for packaging and microbiological testing by expanding its laboratory space at its Wiesbaden, Germany, facility.
An Approach Using Bezier Curves to Control pH and Decrease Enzyme Inactivity
May 2nd 2006Using Bezier curves, an experimental process controller has been developed for biosynthesis applications in which the inactivity of a pH-sensitive enzyme must be decreased. By taking into account various control scenarios of pH and growth rate, as well as the physical and chemical characteristics of the environment, a suitable human-machine interface can be developed.
Creating a compelling business case for your LIMS implementation
May 1st 2006This article examines the development of a business case to secure coveted funding for a LIMS implementation. Information on hard cost savings and soft benefits of implementing a LIMS system, and managing the compilation of the cost justification are covered.
Using remote monitoring to boost performance
May 1st 2006The evolution of sophisticated monitoring systems has been accelerated because of stringent EU legislation surrounding the pharmaceutical industry and the escalating demand for preventative maintenance techniques. This article gives an overview of the benefits of implementing these systems in pharmaceutical manufacturing.
Survival of B. subtilis spores in Dicalcium Phosphate, Lactose, and Corn Starch
April 20th 2006The survival of Bacillus subtilis spores in dicalcium phosphate, lactose, and corn starch and in their binary mixtures depends on the compressional properties of these materials and on parameters involved during the tableting process, including compression speed.
Scaling down biopharmaceutical operations Part 1: Fermentation
April 1st 2006Creation and qualification of scale-down models are essential for performing several critical activities that support process validation and commercial manufacturing. As shown in Figure 1, these activities include process characterization and production support studies that are performed to evaluate column and membrane lifetimes, demonstrate clearance of host-cell impurities and viruses and troubleshoot manufacturing issues. While the underlying fundamentals are relatively the same as those when scaling up, some unique considerations should be taken when scaling unit operations down.4
Viral filtration of plasma-derived human IgG
March 1st 2006Human plasma provides a rich source of therapeutic medicines, including gamma globulins, coagulation factors, albumin, alpha anti-trypsin and others. In 2001, sales of immuno gamma-globulin (IgG) were estimated at $2 billion with a production rate of 50 metric tons for the year.1 A number of therapeutic products have been introduced including Gammimune from Bayer, RhoPhylac from ZLB Behring and Octagam from Octapharma.
Adsorption of small drug particles at the surface of large excipients
January 1st 2006Applications of adsorption of small drug particles at the surface of large excipients were introduced, and different factors affecting adsorption process were discussed and summarized. Several examples of adsorbing drugs to excipients to increase dissolution rate were exhibited in this article.
