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

使用CO2恒温摇床解决人胚肾－293－(HEK293)－细胞结团问题
人胚肾 293 (HEK293) 细胞在重组蛋白表达中是最常见的宿主细胞。 这类细胞能够表达大量的膜蛋白，如 G 蛋白偶联受体 (GPCR) ，是无法在最常见的生物制药生产宿主，如：中国仓鼠卵巢 (CHO) 细胞中作表达。 HEK293 虽然是蛋白表达的极好宿主，然而 HEK293 细胞
