jetPEI®-FluoF is a fluorescein-conjugated linear polyethylenimine derivative (excitation at 490 nm; emission at 520 nm). It was especially designed to visualise transfected cells using confocal or normal fluorescence microscopy and FACS (Fig.1).

jetPEI®-FluoR is a tetramethylrhodamine-conjugated linear polyethylenimine derivative (excitation at 550 nm; emission at 575 nm). This fluorescent jetPEI® is well-suited for double labeling and colocalization experiments with green labels (e.g. green fluorescent proteins, plasmids labeled with green fluorescent intercalating agent, fluoresceinoligonucleotide conjugates, etc…).
