Xcellerex’s XDRbioreactors are well suited for production processes that require the use of anchorage-dependent cell lines grown on microcarriers. The bioreactor agitation assembly is the driver for these factors. To assure robust bioreactor operation, the M40Eimpeller was designed to perform well above the minimal mixing constraint for uniform gas distribution and fluid homogeneity and well below the maximum shear constraint to assure a viable and productive cell population. Cell lines such as Vero, MDCK, and…
