ProtocolforCellFusion
Healthy Sp2/0 cells should be rapidly growing by this time. Sp 2/0 cells should be started about two weeks before the cell fusion. Every two days, they should be centrifuged at a 64.4 xg on the IEC clinical centrifuge (in 50 ml tubes) for two minutes. The media should be removed and the cells resuspended in fresh media. This ensures that only the healthiest cells will fall to the bottom of the tube. Centrifugation at......阅读全文
