    • Methods and systems of harvesting a cell product from a cell culture by culturing cells in a fluid medium until the cells have produced a cell product at a harvest concentration are disclosed. The cells are cultured in a cell culture system including a bioreactor connected to an ATF device. The methods include draining fluid medium from the bioreactor through the outlet and the ATF device until the bioreactor volume reaches a predetermined volume, and the ATF column yields at an ATF outlet a liquid containing cell product and passes fluid medium with a concentration of cell product that is lower than the harvest concentration back into the bioreactor, extracting the liquid containing cell product from the ATF outlet, refilling the bioreactor with sterile phosphate buffered saline or fluid medium without any cell product, and repeating steps until a desired amount of cell product has been removed.
    • 通过在流体培养基中培养细胞直至细胞已经以收获浓度产生细胞产物从细胞培养物中收获细胞产物的方法和系统被公开。 细胞在包括连接到ATF装置的生物反应器的细胞培养系统中培养。 该方法包括从生物反应器中通过出口和ATF装置排出流体介质,直到生物反应器体积达到预定体积,并且ATF柱在ATF出口处产生含有细胞产物的液体并且使细胞产物的浓度 低于回收到生物反应器中的收获浓度,从ATF出口提取含有细胞产物的液体,用无菌磷酸盐缓冲盐水或无细胞产物的流体介质重新填充生物反应器,并且重复步骤直到获得所需量的细胞产物 除去。
