Five mouse-human hybridomas, H2, H3, V1, V2 and V6 cells secreting anti-virus human monoclonal immunoglobulin G (IgG) were cultured in serum-free media at high density in a settling perfusion culture vessel with an inner cell sedimentation zone. The H2, H3 and V6 cells reached a density of 107 cells

โฆ Synopsis
Two mouse myeloma cell lines which were transfected with chimeric mouse variable-human constant immunoglobulin heavy and light chain genes have been cultured at high cell density in a settling perfusion culture vessel to produce chimeric antibody specific for human common acute lymphocytic leukemia antigen (cALLA).
J558L transfectant proliferated well in a serum-free medium (ITES-eRDF) to a viable cell density of 3.7 x 107 cells/ml and produced chimeric antibody to a maximum value of 60 Ixg/ml in 120 ml scale vessel. X63Ag8.653 transfectant reached a density of 1.9 โข 107 cells/ml in 1.2 1 scale vessel in serum supplemented medium (10% FCS-eRDF) and produced chimeric antibody which consisted of chimeric gamma and chimeric kappa chains to a maximum value of 5.8 gg/ml.

A simple high density cell culture system is described which demonstrates many of the features of commercially available hollow-fibre systems, but without the need to invest in a dedicated system.
