Compact Cell Settlers for Perfusion Cultures of Microbial (and Mammalian) Cells

Biosafety of Mammalian Cell Cultures

Mammalian cell cultures for biologics manufacturing.

Biopharmaceuticals represent a growing sector of the pharmaceutical industry, and are used for a wide range of indications, including oncology and rheumatology. Cultured mammalian cells have become the predominant expression system for their production, partly due to their ability to complete the posttranslational modifications required for drug safety and efficacy. Over the past decade, the pr...

Simpler noninstrumented batch and semicontinuous cultures provide mammalian cell kinetic data comparable to continuous and perfusion cultures.

Perfusion culture optimization in multiple noninstrumented small-scale flasks allows reduced expense and time associated with process development. These cultures normally use a different process mode because at small scales it is not practical to retain the cells for medium perfusion. In this work, the kinetics of growth, nutrient consumption, metabolite, and product formation were compared in ...

A novel isolated dual perfusion/superfusion heart model for physiological and pharmacological evaluation of mammalian heart preparations

Abstract Introduction: Isolated perfused heart models such as perfusion and superfusion are commonly used for mammalian heart research. However, there are several fundamental limitations in the current techniques. In perfusion model, a suitable cannula is connected to the aorta and the perfusion is retrogradely performed. But, electrode displacement is a potential unwanted event resulted fr...

IMMOBILIZATION OF MICROBIAL CELLS FOR THE PRODUCTION OF ORGANIC ACIDS

Techniques of immobilization of microbial- cells have been established by multifunctional reagents such as glutaraldehyed on a solid support. Immobilized cell reactor was designed to demonstrate stability of cross linking of whole cells for the production of organic acids. An eighty-six percent conversion of glucose was obtained for an eight hour retention time. The immobilized cell reacto...
