In both cases, the cells should be in mid-logarithmic growth phase with high (>90) viability. Success of the adaptation method will depend upon the particular hybridoma cell line and the culture conditions employed. The major cell culture application areas for Cytopore are production of recombinant products and monoclonal antibodies from CHO, BHK, NSO and hybridoma cells.More information on optimizing culture conditions and troubleshooting is found in Section 11. In order to define therole which Bcl-xL plays in hybridoma cultures, we usedthe Sp2/0-Ag14 cell line.

Troubleshooting. Hybridoma Cells Hybridoma cells are developed in culture by a suc-cessful fusion of a spleen lymphocyte and a myeloma cell. The fused hybrid cells survive culture in a selec-tive media such as HAT whereas the other cells die. Based on the formation kinetics of monoclonal antibody, the bench-scale culture of hybridoma cells in a bioreactor was optimized by the application of perfusion culture mode, the supplement of potassium acetate, and the fortification of nutrients. The hybridomas can be grown in culture, each culture starting with one viable hybridoma cell, producing cultures each of which consists of genetically identical hybridomas which produce one antibody per culture (monoclonal) rather than mixtures of different antibodies (polyclonal). keywords "cell culture, flow cytometry, Hybridoma, monoclonal antibody", author "Sankar Sen and Hu, Wei Shou and Friedrich Srienc"number "8", ty - jour.
