Flp-In™ 293 cell line is designed for rapid generation of stable cell lines that ensure high level expression of your protein of interest from a Flp-In™ expression vector. These cells contain a single stably integrated FRT site at a transcriptionally active genomic locus. Targeted integration of a Flp-In™ expression vector ensures high-level expression of your gene of interest. Flp-In™-293 cell line was created by transfecting the parent cell lines with pFRT⁄lacZeo and selecting for stable Zeocin™- resistant clones.

Flp-In™-293 cells work well with Flp-In™ vectors that express a gene from the CMV promoter (e.g., pcDNA™5⁄FRT, pcDNA5⁄FRT⁄V5-His-TOPO™, and pSecTag⁄FRT⁄V5-His-TOPO
