TRC ‐ transfection ready cells are cryopreserved at a highly receptive state and can be transfected with plasmid DNA instantly after thawing. There is no need to expand or passage the cells before DNA transfer. Simply add your transfection mix to the recovered cells (reverse transfection) in order to obtain highly consistent transfection results. TRCs are compatible with common transfection protocols and are available in different formats from typical mammalian host cell lines. For superior results TRCs are provided in a kit with Viromer®, a polymeric reagent that impoves the bioavailability of the transfected DNA.
