The cell viability was regularly checked every few days. The lowest efficiency was observed for the DVD antibody Fig. Protein Expr. Previously, other protocols have recommended to harvest after 7 days [ 13 ]. This article has been cited by other articles in PMC. However, this cell line is not commercially available anymore and patents restrict its commercial use. The published protocols of PEI transfection which result in similar yields as those reported in the present study have used HEKE cells [ 561819 ].
