  • Patent number: 10723993
    Abstract: A cell culture system for the production of cells and cell derived products includes a reusable instrumentation base device incorporating hardware to support cell culture growth. A disposable cultureware module including a cell growth chamber is removably attachable to the instrumentation base device. The base device includes microprocessor control and a pump for circulating cell culture medium through the cell growth chamber. The cultureware module is removably attached to the instrumentation base device. Cells are introduced into the cell growth chamber and a source of medium is fluidly attached to the cultureware module. Operating parameters are programmed into the microprocessor control. The pump is operated to circulate the medium through the cell growth chamber to grow cells or cell products therein. The grown cells or cell products are harvested from the cell growth chamber and the cultureware module is then disposed.

  • Publication number: 20150111252
    Abstract: The subject invention pertains to methods and apparatus for the production and purification of cell products, such as immunoglobulins. One aspect of the invention is an integrated cell culture and purification apparatus for the growth and maintenance of cells and the harvest and purification of cell products, such as immunoglobulins. Thus, the apparatus integrates a cell culture function with a purification function. Other aspects of the invention pertain to an automated method for producing immunogenic compositions such as vaccines.

  • Patent number: 6001585
    Abstract: A "micro" hollow fiber bioreactor and method of use are provided for use in screening different cell lines and process conditions. The bioreactor includes the use of an oxygen permeable (e.g., silicone rubber) tube sealably containing a hollow fiber bundle, in order to create an extracapillary space to provide a medium reservoir and an intracapillary space for the growth of cells. The bioreactor avoids the need for oxygen or medium pumps or supply systems, and permits multiple cell lines, and/or multiple conditions to be evaluated simultaneously. Preferably, the tube has an oxygen permeability of between about 100.times.10.sup.-10 to about 10,000.times.10.sup.-10 (cc-mm/sec-cm.sup.2 -cm Hg), the extracapillary space provides a medium reservoir of about 1 ml to about 100 ml, the intracapillary space provides a cell culture volume of about 0.1 ml to about 1 ml, the hollow fibers have a molecular weight cut off from about 1 kD to about 1,000 kD and a pore size of from about 0.

  • Patent number: 5510261
    Abstract: A neuraminidase enzyme with unusually high activity under extracellular culture conditions has been discovered in Chinese hamster ovary (CHO) cells and other types of cells. By affecting the neuraminidase activity of the cell culture, the degradation of glycoprotein oligosaccharides produced by these cultured cells can be controlled.
