Abstract
In order to control the four primary variables (cells, serum, medium and physical conditions) in a cell or virus growth system it is important to have a reliable and constant positive control with which to compare any variable of the system components. The use of aliquots of a frozen cell population (stored at -136 degrees C) for this purpose is the subject of this paper. Using such cells, tests have been established for the control of sera, media, cell susceptibility and the quality of serum treated DEAE Sephadex A50 beads.
