4Cell® Xtra CHO Media System
The Starting Kit of the 4Cell® XtraCHO Media System includes all the necessary medium components from adapting the cells to fed-batch production at a cultivation volume of 3L. For larger volumes all individual system components are available in different formats, in liquid (bottle and bag) and powder.
4Cell® XtraCHO Stock & Adaptation Medium
It allows the cultivation or media adaptation of cells. Lacking certain metabolites, the cultivation medium exerts a strong selection pressure on cells and shortens the time consuming adaptation to fed-batch culture.
4Cell® XtraCHO Production Medium
It is a non-selective production medium for batch or fed-batch culture. It can be used for effective cultivation of recombinant CHO-DG44 cells and other CHO cell lines to produce high yield of the active protein.
4Cell® XtraCHO Feed Medium A & B
Both feed additives are especially matched to the production medium. Combining those increases fed-batch productivity 3- to 5-fold compared to batch culture conditions.
