Cell Harvesting Procedure. The goal is to remove the cells from the plastic substrate and break cell-to-cell bonds as gently as possible. There are several variations of this protocol dependent on the methods pouring, pumping, etc. you prefer for removing and adding solutions to the Corning CellSTACK chambers. This protocol is designed for ...

As a result, the use of hydrocyclones for harvesting cell cultures can be expected to reduce investment costs as well as operating costs, which will also be reflected in a lower product price. These advantages are also valid when membrane filters and settlers are used for comparison. Compared to membrane filters, hydrocyclones have the ...
