||The cells from 6 insect cell lines Bm-21E-HNU5, BCI RL-Px-HNU3, Pa-E-HNU6,
Pr-E-HNU9(A), Pr-E-HNU9(C) and IPLB-Sf-21, were stored in a refrigerator
at 4-10 Celsius for over 60 days, and revived except for Pr-E-HNU9(C)
cells floating in culture. The cells from Pa-E-HNU6 and Pr-E-HNU9(A),
growing attached to surface of the flasks tighter than the other cells,
were stored for 125 and 158 days respectively. Feeding the cells with
fresh growth media at regular intervals during storage helped to prolong
storage of the cells.
