Abstract:The effect of cryopreservation on the survival of luc gene transfected bluegill sunfish fibroblast (BF-2) cells was investigated. Propane-1,2-diol was found to be the least toxic cryoprotectant when compared with DMSO and methanol. Both propane-1,2-diol and DMSO are effective in protecting cells from freezing damage. Whilst there were no significant differences in cell survival between cryoprotectant concentration (10 or 15%) and culture age used in this study, 7-day old culture appeared to be more resistant to freezing without cryoprotectant when compared with 3- and 14-day old culture. The highest cell survival values obtained with propane-1,2-diol (10%) and DMSO (10%) protection were 96.2 ± 1.2% and 94.0 ± 3.1% respectively. Initial subsequent cell growth after cryopreservation was slower than their non-frozen controls. The survival of transfected BF-2 cells (BF-2/luc1) after cryopreservation were very similar to those obtained with wild type cells being: 94.0 ± 3.1% and 95.2 ± 1.5% respectively with 10% DMSO protection. These results suggested that genetically modified fish cell lines may be equally amenable to cryopreservation as the wild type.
