EX-CELL VPRO is an animal-protein free, serum-free medium developed for the long-term growth of Human Embryonic Retinoblast cells (PER.C6™ and related cell lines). The cells can be subcultured directly into EX-CELL VPRO from serum-free media with little or no adaptation. PER.C6 cells can be grown as suspension cultures either in shaker flasks or roller bottles, with roller bottles being the preferred culture system. Suspension cultures can be maintained, without refeeding, for approximately 10 days and can be carried for more than 20 passages with no loss of viability.
