I am trying since 2 months to generate HeLa Flp-In TRex cell lines, but failed. If someone have a detailed protocol, including cell number to seed, transfection method used, antibiotic concentration etc, could you kindly share.

Cell culture HeLa Flp-In T-REx (a kind gift from Matthias Hentze) and 293 Flp-In T-REx cells (Thermo Fisher Scientific) were cultured in Dulbecco’s Modified Eagle’s Medium (Gibco) supplemented with 10% fetal bovine serum (FBS;standard FBS hereafter) (Gibco) at 37°C in a humidified 5% CO2 atmosphere. Where indicated, certified tetracycline-free FBS (Clontech and Biochrom GmbH) was used instead of standard FBS. Cells were tested for mycoplasma contamination.
